3 * dll/jump.funcs: Add new jumptable entries for
4 ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
5 ext2fs_badblocks_equal.
7 * tst_badblocks.c: Update test program to test
8 ext2fs_read_bb_FILE2 and ext2fs_write_FILE.
10 * write_bb_file.c (ext2fs_write_bb_FILE): New function which
11 writes out bad blocks list to a file.
13 * read_bb_file.c (ext2fs_read_bb_FILE2): Add new function which
14 changes the callback function to take two additional
15 arguments; a private blind pointer supplied by the caller,
16 and pointer to a char * containing a pointer to the
19 * badblocks.c (ext2fs_badblocks_equal): Add new function which
20 returns true if two badblocks list are equal.
22 * Makefile.in: Remove explicit link of -lc in the shared library.
23 (It shouldn't be necessary, and is harmful in some cases).
25 2000-06-10 Theodore Ts'o <tytso@valinux.com>
27 * getsize.c (main): Add debugging code under #ifdef DEBUG
29 2000-05-27 Theodore Ts'o <tytso@valinux.com>
31 * mkdir.c (ext2fs_mkdir): Read the parent directory's inode
32 earlier, so that if there's an error reading it, we can
33 more cleanly back out of the operation.
35 2000-05-25 <tytso@snap.thunk.org>
37 * getsize.c (ext2fs_get_device_size): Use open64() instead of
38 open() if it exists. Under linux, manually define the
39 ioctl for BLKGETSIZE if it isn't already defined and it's
42 * unix_io.c (unix_open): Use open64() instead of open() if it
45 * llseek.c: Simplify header includes of unistd.h. If lseek64 is
46 available (and prototypes are defined) use it in
49 * Makefile: Add hack dependency rule so that parallel makes work
52 2000-05-18 Theodore Ts'o <tytso@valinux.com>
54 * ext2fs.h: Add appropriate ifdef's to support C++ compilation.
56 2000-04-03 Theodore Ts'o <tytso@valinux.com>
58 * block.c: Readibility tweak in conditionals involving
61 * ext2fs.h: Use AUTOCONF SIZEOF_* macros if available to determine
62 how to define __s64 and __u64. Turn off "compression is
63 experimental" warning if the cpp macro
64 I_KNOW_THAT_COMPRESSION_IS_EXPERIMENTAL is defined.
66 2000-02-11 <tytso@snap.thunk.org>
68 * ext2fs.h: Define EXT2FS_COMPRESSED_BLKADDR and HOLE_BLKADDR.
69 Conditionally include Compression as a supported type if
70 ENABLE_COMPRESSION (via --enable-compression) is turned on.
72 * swapfs.c (ext2fs_swap_super): Swap the compression usage bitmap.
74 2000-02-08 <tytso@snap.thunk.org>

77 ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
78 ext2fs_mark_inode_bitmap, ext2fs_unmark_inode_bitmap):
79 Change to return the previous state of the bit that is
80 being marked or unmarked. For speed optimization.
82 2000-02-02 Theodore Ts'o <tytso@valinux.com>
84 * getsize.c, ismounted.c: Remove unneeded include of linux/fs.h
86 * swapfs.c: Remove #ifdef HAVE_EXT2_INODE_VERSION since it's not
87 needed any more; we know it will always be i_generation.
88 Add support for swapping the high bits of the uid and gid.
90 1999-11-19 <tytso@valinux.com>
92 * mkdir.c (ext2fs_mkdir): Only update the parent's inode link
93 counts if the link was successful. Patch suggested by
96 * Makefile.in (distclean): Remove TAGS and Makefile.in.old from
99 1999-11-10 <tytso@valinux.com>
101 * Release of E2fsprogs 1.18
103 1999-11-08 <tytso@valinux.com>
105 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
106 since ext2fs_badblocks_list_free was moved to freefs.c.
108 * tst_badblocks.c: Use the newer badblocks API names. Add
109 duplicate blocks to the test inputs to test dealing with
110 adding blocks which are already in the badblocks list.
112 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
113 of the list, use a shortcut O(1) operations instead of an
114 O(n) operation. (Idea suggested by David Beattie.)
116 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
117 of badblocks_list_free(), to save a procedure call.
119 1999-10-26 <tytso@valinux.com>
121 * Release of E2fsprogs 1.17
123 1999-10-26 <tytso@valinux.com>
125 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
126 seem to handle ~0UL the same way as they used to.
128 1999-10-25 <tytso@valinux.com>
130 * nt_io.c (_OpenNtName): Open the device using
131 FILE_SYNCHRONOUS_IO_NONALERT instead of
132 FILE_SYNCHRONOUS_IO_ALERT
133 (nt_open): At the end of the device open routine, unlock
134 the drive but do not dismount it.
136 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
139 1999-10-22 <tytso@valinux.com>
141 * Release of E2fsprogs 1.16
143 1999-10-22 <tytso@valinux.com>
145 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
147 * link.c (ext2fs_link): This call now uses the low three bits of
148 the flags parameter to pass the directory filetype
149 information; it will set the directory entry FILETYPE
150 information if the filesystem supports it.
152 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
153 option is set, then create the '.' and '..' entries with
154 the filetype set to EXT2_FT_DIR.
156 1999-09-24 <tytso@valinux.com>
158 * nt_io.c: New file which supports I/O under Windows NT.
160 1999-09-07 <tytso@valinux.com>
162 * ext2fs.h: Add new fields for journalling and define new
163 feature bits used by newer filesystems: IMAGIC_INODES,
164 HAS_JOURNAL, RECOVER.
166 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
167 we update the inode block count and size files so that the
168 block count field is updated correctly when we create an
171 1999-07-18 Theodore Ts'o <tytso@valinux.com>
173 * Release of E2fsprogs 1.15
175 1999-06-23 <tytso@valinux.com>
177 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
178 kernels that use i_generation instead of i_version. Patch
179 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
181 1999-06-21 <tytso@valinux.com>
183 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
184 directory entry before calling the callback function.
185 This should prevent some core dumps of insufficiently
186 paranoid callback functions.
188 1999-05-29 <tytso@rsts-11.mit.edu>
190 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
192 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
193 that we don't handle writing yet (we do). Fixed bug where
194 we weren't allocating a big enough buffer for ext2_bmap.
196 1999-05-03 <tytso@rsts-11.mit.edu>
198 * openfs.c (ext2fs_open): Check to make sure that the number of
199 blocks per group is not zero --- if so, it must be a bad
202 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
204 * Release of E2fsprogs 1.14
206 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
208 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
209 the inode number is zero; if it's zero, return
210 EXT2_ET_BAD_INODE_NUM.
212 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
214 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
215 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
218 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
220 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
221 non-Linux case to use EINVAL by default, unless it isn't
222 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
225 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
227 * Release of E2fsprogs 1.13
229 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
231 * Makefile.in: Updated dependencies.
233 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
235 * initialize.c (ext2fs_initialize): Make sure that we allocate
236 enough inodes so that we can make a valid filesystem.
238 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
240 * rw_bitmaps.c: Fixed signed/unsigned warnings.
242 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
243 function declaration.
245 * dblist.c (make_dblist): Add safety check in case the dblist
246 pointer passed in is null (in which case, assign it to
247 fs->dblist). Fixed some signed/unsigned warnings.
249 * bmap.c: Make addr_per_block be of type blk_t to avoid
250 signed/unsigned warnings.
252 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
253 function declaration.
255 * get_pathname.c (get_pathname_proc): Use return value from
256 ext2fs_get_mem, instead of checking if &gp->name is

260 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
261 from the function declaration.
263 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
264 return the error directly instead of jumping to the
265 cleanup routine, since we don't need to do any cleanup.
267 * alloc_table.c (ext2fs_allocate_group_table): Make this
268 function take a dgrp_t for its group argument.
270 * ext2fs.h: Make dgrp_t an __u32 type, and make
271 fs->desc_group_count be of type dgrp_t.
273 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
275 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
276 than 10 blocks when we need to expand the size of the
279 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
281 * Release of E2fsprogs 1.12
283 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
285 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
286 appropriate for all of the block group copies, so that
287 it's clear where the beginning of the filesystem is on the
288 disk. (For when the partition table gets scrod.)
290 * ext2fs.h: Change the name of the feature from
291 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
292 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
294 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
296 * inode.c (get_next_blockgroup): Fix bug where if
297 get_next_blockgroup() is called early because of a missing
298 inode table in a block group, the current_inode counter
299 wasn't incremented correctly.
301 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
303 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
304 against a completely trashed bad block inode.
306 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
308 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
309 the stride length hits a bad value, we retry the block
310 allocation starting at the beginning of the block group.
312 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
313 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
314 e2_blkcnt_t to avoid collision with LFS API.
316 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
318 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
319 way that avoids overflows on disk sizes greater than 4GB.
321 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
323 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
324 return type for comparison functions for qsort.
326 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
329 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
331 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
334 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
335 evade a potential problem with glibc's header files trying
336 to spike out linux/types.h.
338 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
339 include the old size of the memory, which is needed for
340 some braindamaged memory allocation systems that don't
343 * badblocks.c (ext2fs_badblocks_list_add):
344 bb_inode.c (clear_bad_block_proc):
345 dblist.c (ext2fs_add_dir_block):

349 pass the old size of the memory to be resized to
352 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
354 * Makefile.in: Change to use new installation directory variables
355 convention. Fix uninstall rules to take $(DESTDIR) into
358 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
360 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
361 with 32 bit longs, then we need to manually define __s64
362 and __u64, since the current kernel header files don't
363 define these if __STRICT_ANSI__ is defined. This is a
364 problem if we are compiling with full GCC warnings, since
365 we do need 64 bit support.
367 * Makefile.in (OBJS): Remove bmove.o from files to be built,
368 since we're not using ext2fs_move_blocks() and there
369 is some question as to its usefulness in its current
372 * bmap.c (block_bmap): Remove unused function.
374 * bmove.c (process_block): Fix -Wall warning.
376 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
378 * block.c (ext2fs_block_iterate3): Make the ref_offset field
379 contain the offset into the inode.i_blocks array when
380 ref_block is zero. Since we haven't done a formal
381 release of e2fsprogs since block_iterate2 was first
382 introduced, I removed block_iterate2, and renamed
383 block_iterate3 to be block_iterate2.
385 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
386 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
387 use of block_iterate and block_iterate2 to
388 block_iterate2 with the new prototype for the
389 interator function. (using blkcnt_t forr blockcount)
391 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
393 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
394 s_prealloc_blocks, s_prealloc_dir_blocks). Added
395 conditional defines of new features COMPAT_DIR_PREALLOC,
396 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
397 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
398 the library to declare that we support COMPAT_DIR_PREALLOC,
399 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
401 * fileio.c: Rename function ext2fs_file_llseek to be
402 ext2fs_file_lseek, which is more accurate.
404 * block.c: Add new function ext2fs_block_iterate3 which calls
405 the iterator function with the blockcount argument of
406 type blkcnt_t. This version of the function is
407 allowed to handle large files; the other fucntions are
410 * ext2fs.h: Add new type blkcnt_t
412 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
414 * block.c (ext2fs_block_iterate2): Fix bug where the block count
415 field wasn't getting correctly incremented for sparse
416 files when the indirect or doubly-indirect block
417 specified in the inode was zero.
419 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
421 * unlink.c (unlink_proc):
422 * lookup.c (lookup_proc):
423 * link.c (link_proc):
424 * get_pathname.c (get_pathname_proc):
425 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
426 from dirent->name_len, so it can be used for other
429 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
430 and indicate that we have support for this incompatible
433 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
435 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
437 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
439 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
440 number of directories when the block group information is
443 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
445 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
446 inode table is missing so that we catch the case where the
447 first block group is missing.
449 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
452 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
454 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
456 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
458 * test_io.c (test_flush): Add a debugging printf when the flush
461 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
462 read in, return right away.
464 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
466 * bitops.h: Don't try to do i386 inline asm functions if the
469 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
470 instead of linux/types.h, and e2_bitops.h instead of
473 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
476 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
478 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
479 so that we don't need to call get_next_blockgroup() the
480 first time around. Saves a bit of time, and prevents us
481 from needing to assign -1 to current_group (which is an
484 * icount.c (insert_icount_el): Cast the estimated number of inodes
485 from a float to an ino_t.
487 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

497 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
498 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
499 defined, then assume all of the
500 ext2-specific header files are in a flat directory.
502 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
503 all assignments from void * to be compatible with C++.

507 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
508 make sure the contents of the disk are flushed to disk.
510 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
512 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
513 avoid C++ namespace clash.

524 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
526 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
527 paranoid about validating the directory counts from the
528 block group information.
530 * all files: Don't include stdlib.h anymore; include it in
531 ext2_fs.h, since that file requires stdlib.h
533 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
535 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
536 bitmap is loaded, and return an error if it is not.
537 (expand_dir_proc): Only use ext2fs_write_dir_block when
538 writing a directory block, not when writing out a fresh
541 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
543 * Makefile.in, tst_getsize.c: Added new file which is used to test

552 * fileio.c (ext2fs_file_get_size, ext2fs_file_set_size,
553 ext2fs_file_get_fs): New functions added.
556 Fri Oct 31 12:16:52 1997 <tytso@EDT.MIT.EDU>
558 * bitops.c (ext2fs_warn_bitmap, ext2fs_warn_bitmap2): Don't call
559 com_err if OMIT_COM_ERR is defined.
561 Thu Oct 30 11:33:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
563 * Rename new error codes to _ET_ in them for consistency.
565 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
567 * [all files, basically]: Added definition of ext2fs_get_mem,
568 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and
569 changed all library routines to use these wrapper functions.
571 * dblist.c, mkdir.c: use EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND
572 instead of the system error messages.
574 * ext2_err.et.in: Added new error messages EXT2_DIR_EXISTS and
577 * ext2fs.h: Added function declarations and constants for bmap.c

589 * fileio.c: New file which implements simple file reading and
592 * alloc.c (ext2fs_alloc_block): New function which allocates a
593 block, zeros it, and updates the filesystem accounting
594 records appropriately.
596 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
598 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,
599 EXT2_INVALID_ARGUMENT, EXT2_BLOCK_ALLOC_FAIL,
600 EXT2_INODE_ALLOC_FAIL, EXT2_NOT_DIRECTORY
602 * Change various library files to use these functions instead of

607 * llseek.c: Check HAVE_LLSEEK_PROTOTYPE to see whether or not we
608 need to declare llseek().
610 Sun Oct 19 18:56:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
612 * Rename io.h to be ext2_io.h (avoid namespace collisions)
614 * Add #ifdef's for HAVE_SYS_STAT_H and HAVE_SYS_TYPES_H
616 Fri Oct 3 13:35:59 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
618 * llseek.c (ext2fs_llseek): Fix type error for ext2fs_llseek()

630 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
631 padding of the bitmap to be all one's.
633 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
635 * llseek.c: Added missing semicolon to glibc fixup declaration of

643 added a new field to the io_channel (app_data).
645 * io.h: Add a new element to the io_channel structure, app_data.
647 * initialize.c, openfs.c: Set io->app_data to point at the

652 * io.h: Change the prototype of ext2fs_llseek() to use int's
653 instead of unsigned int's.
655 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
656 to make life easer for GNU Libc 2.
658 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
659 filesystem has its bitmaps stored as 32-bit words with bit
660 0 as the LSB of each word. Thus a bitmap with only bit 0
661 set would be, as a string of bytes, 00 00 00 01 00 ... To
662 cope with this, we byte-reverse each word of a bitmap if
663 we have a big-endian filesystem, that is, if we are *not*
664 byte-swapping other word-sized numbers.
666 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

727 icount.c initialize.c inline.c inode.c irel_ma.c link.c
728 llseek.c lookup.c mkdir.c namei.c newdir.c read_bb.c
729 read_bb_file.c rs_bitmap.c rw_bitmaps.c swapfs.c
730 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
731 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
733 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
735 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
736 is zero, then return EXT2_IO_LLSEEK_FAILED.
738 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
740 * Release of E2fsprogs 1.11
742 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
744 * dblist.c (ext2fs_dblist_count): Added new function which returns
745 the number of directory blocks in dblist.
747 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
749 * unix_io.c (unix_flush): Make the io_channel flush function do a
750 fsync to flush the kernel buffers to disk.
752 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
754 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
755 current inode number wasn't being set by the
756 goto_blockgroup function.
758 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
760 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
761 of blocks which need to be moved, and moves those blocks
762 to another location in the filesystem.
764 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
765 bitmap, make sure all of the new parts of the bitmap are
768 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
771 wasn't being returned to the caller.
773 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
774 ext2fs_allocate_group_table() which sets the group tables
775 for a particular block group. The relevant code was
776 factored out of ext2fs_allocate_tables().
778 * dblist.c (make_dblist): Adjust the initial size of the directory
779 block list to be a bit more realistic (ten plus twice the
780 number of directories in the filesystem).
782 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
784 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
785 ext2fs_badblocks_list_test would test the list (and exceed
786 array boundaries) if there were no bad blocks on the bad
787 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
789 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
791 * Release of E2fsprogs version 1.10
793 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
795 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
796 inode and block bitmaps based on the RAID 0 stride
797 parameter (which is passed by mke2fs).
799 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
800 mke2fs to communicate the stride length to
801 ext2fs_allocate_tables()
803 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
805 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
806 systems. (We can't assume that the new filesystem types
809 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
811 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
812 allocate the inode and block bitmaps inside block group at
815 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
817 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
818 filesystem has no free blocks, ext2fs_new_block would loop
821 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
823 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
824 free if refcount goes to zero.
826 * inode.c (create_icache): Initialize refcount to 1.
828 * ext2fsP.h: Added refcount to ext2_inode_cache
830 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
833 * badblocks.c (ext2fs_badblocks_copy): New function to copy a
836 Sun Apr 20 23:19:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
838 * bitmaps.c (ext2fs_copy_bitmap): New function to copy a bitmap.
840 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
842 (unix_close, test_close): Decrement the refcount and only
843 close the io_channel if the refcount goes to 0.
845 * io.h: Add refcount to the io_channel structure. Add new macro
846 interface io_channel_bumpcount() to bump the refcount.
848 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
850 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
851 cache in the filesystem handle, instead of the inode cache
852 in a static variable.
854 * freefs.c: Added static function to free the inode cache (called by
857 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
859 * ext2fs.h: Added pointer to the inode_cache structure.
861 * block.c (block_iterate_ind, block_iterate_dind,
862 block_iterate_tind): If there are holes in the indirect,
863 doubly indirect, or triply indirect blocks, increment the
864 block count field automatically.
866 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
868 * Release of E2fsprogs version 1.09
870 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
872 * version.c (ext2fs_parse_version_string): Check the passed in
873 version string (instead of the hard-coded one).
875 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
876 greater filesystem size, clamp it to prevent allocating a
877 block or inode bitmap beyond the filesystem.
879 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
880 overhead calculation was accidentally removed.
882 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
884 * Release of E2fsprogs version 1.08
886 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
888 * dblist.c (ext2fs_set_dir_block): New function which sets the
889 block of a dblist entry, given the directory inode and
892 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
894 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
895 inode bitmaps at staggered locations across the block
896 groups, to avoid concentrating the bitmaps on a small
897 number of disks when using striped RAID arrays.
899 * initialize.c (ext2fs_initialize): By default, choose the maximum
900 possible number of blocks per group (based on the size of
901 the bitmaps in the blocksize).
903 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
905 * initialize.c (ext2fs_initialize): Add support for
906 EXT2_COMPAT_SPARSE_SUPER feature.
908 * closefs.c (ext2fs_bg_has_super): New function to determine
909 whether or a particular block group should have a
910 superblock and block group descriptor. Used for the
911 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
912 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
913 or not the superblock should be written out for the block
916 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
917 for sparse duplicate superblocks.
919 * version.c (ext2fs_get_library_version): New function which
920 returns the library version.
922 * version.c (ext2fs_parse_version_string): New function which
923 parses a version string and returns a version number,
924 so application programs can compare version numbers as
927 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
929 * icount.c (ext2fs_create_icount): Change function so that it also
930 takes a new argument which contains a "hint" icount
931 structure. This "hint" icount allows the create function
932 to set up the sorted list in advance. This reduces
933 significantly the amount of data moving needed to insert
934 these inodes into the list later.
936 * icount.c (ext2fs_icount_validate): New function which validates
937 that the icount structure's rep invariant.
939 * icount.c (get_icount_el): Completely revamped implementation
940 to subsume put_icount_el(). Put_icount_el() used to
941 use an O(N) implementation to insert in the middle
942 of the icount list. It now uses a O(ln N) to search
943 for where the icount should be inserted, and then uses
944 a memcpy to move the list down (instead of a for loop).
946 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
947 ext2fs_icount_increment, ext2fs_icount_decrement): Check
948 to see if the inode is within bounds; if it isn't, return
951 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
952 when a bad inode number is passed to test_generic_bitmap
953 to be EXT2FS_TEST_ERROR instead of the wrong
956 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
958 * Release of E2fsprogs version 1.07
960 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
962 * Makefile.in (ELF_VERSION): Change version to be 2.2
964 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
966 * alloc.c (ext2fs_get_free_blocks): Change routine to use
967 ext2fs_fast_test_block_bitmap_range().
969 * bitops.h (ext2fs_fast_test_block_bitmap_range,
970 ext2fs_test_block_bitmap_range: New inline functions which
971 test to see whether a contiguous range of blocks is
974 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
976 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
977 use ext2fs_badblocks_* instead of badblocks_*
979 * bb_compat.c: New file which translates between old badblocks_*()
980 names to ext2fs_badblocks_*()
982 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
983 link.c (since e2fsck doesn't use ext2fs_unlink()).
985 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
986 bitmap resizing routine moved from bitmaps.c, since e2fsck
987 doesn't need to use this function.
989 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
990 since e2fsck only needs ext2fs_lookup.
992 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
994 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
995 already set; this is needed so that programs like dump
996 which use the inode scan functions will deal with
997 filesystems that have bad blocks in the inode table.
999 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1001 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
1002 Moved to ext2fsP.h, since it doesn't need to be part of
1003 the public interface.
1005 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
1007 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1009 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
1010 directory block list abstraction. (Code moved from
1013 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
1014 to inode.c (since no one else should be peeking inside it!)
1016 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
1018 * openfs.c (ext2fs_open): Check the feature set in the ext2
1019 superblock, and refuse to open filesystems if they contain
1020 incompatible features. (Can be overriden with the
1023 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1025 * block.c (ext2fs_block_iterate2): Added new function
1026 ext2fs_block_iterate2 which changes the function
1027 signature of the callback function to include the
1028 referencing block and offset.
1030 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
1031 ext2fs_inode_scan_goto_blockgroup which allows an
1032 application to jump to a particular block group while
1033 doing an inode scan.
1035 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
1037 * dirblock.c: Include string.h, since we use memcpy().
1039 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1041 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
1042 a long not an int; this doesn't matter on i386 machines,
1043 but it does on Alpha's.
1045 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1047 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
1048 table pointer is NULL, then return an error indicating
1049 that the inode table is missing.
1050 (get_next_blockgroup, get_next_blocks,
1051 ext2fs_get_next_inode): Don't treat a missing inode table
1052 as permanent error. Return MISSING_INODE_TABLE, but as an
1053 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
1055 * rw_bitmaps.c (ext2fs_write_block_bitmap,
1056 ext2fs_write_inode_bitmap): If the inode or block bitmap
1057 block is zero, then don't write out the inode or block
1058 bitmap. The idea here is to avoid stomping on the
1060 (read_bitmaps): If the inode or block bitmap block is
1061 zero, then fill in that portion of the inode or block
1062 bitmap with all zeros.
1064 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
1065 blocks in inode table when the inode table size is
1066 non-standard (and can therefore span blocks).
1068 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1070 * alloc.c (ext2fs_new_block): Fix fencepost error in
1071 ext2fs_new_block; make sure we don't try to allocate the
1072 first block beyond the end of the filesystem.
1074 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1076 * inode.c (check_for_inode_bad_blocks): New function called by
1077 get_next_blocks() to avoid reading in bad blocks marked in
1078 fs->badblocks. Inodes located in bad blocks are returned

1098 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
1099 blocks to the badblock list in sorted order. This allows
1100 badblocks_list_test to be coded using a binary search for

1110 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1113 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1114 set, then only write out the master superblock.
1116 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1118 * block.c (ext2fs_block_iterate): Fixed bug which caused

1154 * namei.c (ext2fs_follow_link): New function.
1155 (ext2fs_namei): Extended to have support for chasing
1156 symbolic links. ext2fs_namei() still returns an inode
1157 which is a symbolic link. Symbolic links are only chased
1158 while resolving the containing directory. To chase
1159 symbolic links of the final result, use
1160 ext2fs_follow_link().

1171 * initialize.c (ext2fs_initialize): On systems where the byte
1172 order is not i386 compatible, set the swap_byte flag.
1174 * inode.c (inocpy_with_swap): Check to see if inode contains a
1175 fast symlink before swapping the inode block fields. This
1176 required adding a new argument to inocpy_with_swap to
1177 determine whether the mode field is in host order or not.
1179 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1181 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On

1192 (including the HURD translator).
1194 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1196 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.

1208 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1210 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1211 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1212 that's a basic value that must be correct for the rest of
1213 the library to work.
1215 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1218 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1268 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1269 to avoid conflicts with with kernel include files. Also
1270 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

1295 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1298 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>

1327 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1328 Move these functions to freefs.c.
1330 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1331 descriptors shadow memory to keep purify quiet. (This
1332 also has the nice benefit that the unused portion of the
1333 shadow descriptors are zeroed out.)
1335 * dirblock.c (ext2fs_write_dir_block): We need to use
1336 dirent->rec_len *before* it's byteswapped to find the
1337 location of the next directory structure!
1339 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1340 cause ext2fs_new_inode to loop infinitely if we're trying
1341 to allocate an inode in group #0 and there are no free
1342 inodes at all in the system.
1344 * closefs.c: #include <errno.h> if it exists.
1346 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

1378 the superblock and group descriptors before writing it out.
1380 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1381 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1382 and group descriptors.
1384 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1385 to desp ext2 filesystem structures.
1387 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1388 supplied by Pete A. Zaitcev so that the C language
1389 versions of these functions are more portable. They will
1390 now work on both little and big endian systems, and the
1391 assumption that 32-bit integers are used is gone.
1393 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1394 doing byte swapping.
1396 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

1410 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1411 if the magic number is correct, it will be allocated.
1413 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1415 * block.c (block_iterate_ind, block_iterate_dind,
1416 block_iterate_tind): Don't recompute block_nr each loop;
1417 just increment it! Factor check of BLOCK_FLAG_APPEND out
1418 of the loop. Factor mask of BLOCK_CHANGED into changed
1419 variable out of the loop. (block_iterate_ind, in
1420 particular, gets called a lot, so every little
1421 optimization helps.)
1423 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1425 * block.c (block_iterate_ind, block_iterate_dind,

1437 ext2fs_get_inode_bitmap_end): Add new accessor functions
1438 which return the start and end points of the bitmaps.
1440 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1442 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1443 instead of llseek. The errno if the offset is too large
1444 and lseek is not supported should be EINVAL, not -EINVAL.
1446 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1448 * Makefile.in: Added support for ELF shared libraries.
1449 Fixed typos in the compilation rules.

1464 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1465 the S_*, which are normally defined in <sys/stat.h>. This
1466 allows us to compile e2fsprogs on a non-Linux system,
1467 which may have a different value for S_IFDIR.
1469 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1471 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1472 this is a user-mode application!
1474 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1476 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1477 __linux__ so that non-linux systems won't see it.

1480 * badblocks.c: Ditto.
1481 * bb_inode.c: Ditto.
1484 * expanddir.c: Ditto.

1501 * initialize.c (ext2fs_initialize): Don't allow more than one
1502 bitmaps's worth of inodes in a group.
1504 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1506 * llseek.c (ext2_llseek): Added error checking to the llseek()
1507 compat code to protect against overflow. This only
1508 applies to 1.0 and early 1.1 kernels, which don't support
1509 the llseek() system call.
1511 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1513 * unix_io.c (unix_open): Initialize the read_error and write_error
1514 io_channel pointers to be null.
1516 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1517 found, clear it but don't try to update the filesystem
1518 accounting information, since that's hopeless anyway.
1520 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1521 bloblock_iterate_tind): Check to see if the indirect blocks are
1522 valid before trying to read them.

1528 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1529 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1530 illegal block or inode number is passed in, return instead
1531 of trying to test, set, or clear the bit.
1533 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1535 * Makefile: Added a dummy install target in case shared libraries

1578 * namei.c (ext2fs_dir_iterate, ext2fs_lookup, ext2fs_namei):
1579 * link.c (ext2fs_link, ext2fs_unlink):
1580 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
1581 ext2fs_write_inode, ext2fs_get_blocks,
1582 ext2fs_check_directory):
1583 * get_pathname.c (ext2fs_get_pathname):
1584 * expanddir.c (ext2fs_expand_dir):
1585 * block.c (ext2fs_block_iterate):
1586 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1587 ext2fs_allocate_block_bitmap):
1588 * bb_inode.c (ext2fs_update_bb_inode):
1589 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1590 * check_desc.c (ext2fs_check_desc):
1591 * closefs.c (ext2fs_close, ext2fs_flush):
1592 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1597 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1598 openfs.c into its own file.
1600 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1601 structure magic numbers.
1603 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1604 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1605 someone uses the -b option to specify the use of the backup
1606 superblock --- this usually means that the main superblock is
1610 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1611 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1612 revision level to the superblock.
1614 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1621 * initialize.c: Completely revamped the inode and block bitmap
1622 structures, so that they can be better chance of being extensible
1623 in a shared library. They are now their own type, instead of
1624 being a char *. Also, the function signatures of
1625 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1626 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1627 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1628 changed to eliminate the ext2_filsys argument, since it is no
1631 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1633 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1634 system call if available.
1636 * llseek.c: new file. This is the stub calling the llseek system
1637 call which allows supports for 2GB+ file systems.
1639 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1640 the creator operating system.
1642 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1644 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1645 the group descriptor statistics in addition to everything else.
1646 This relieves mke2fs of the responsibility of doing it.
1648 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1649 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1650 not the generic C function equivalents should be included or not.
1652 * openfs.c (ext2fs_open): If a superblock is specified, then use
1653 the backup group descriptors that go along with this superblock,
1654 instead of using the primary group descriptors. This allows
1655 e2fsck to recover filesystems where the primary group descriptors
