1 1999-09-07 <tytso@valinux.com>
3 * ext2fs.h: Add new fields for journalling and define new
4 feature bits used by newer filesystems: IMAGIC_INODES,
7 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
8 we update the inode block count and size files so that the
9 block count field is updated correctly when we create an
12 1999-07-18 Theodore Ts'o <tytso@valinux.com>
14 * Release of E2fsprogs 1.15
16 1999-06-23 <tytso@valinux.com>
18 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
19 kernels that use i_generation instead of i_version. Patch
20 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
22 1999-06-21 <tytso@valinux.com>
24 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
25 directory entry before calling the callback function.
26 This should prevent some core dumps of insufficiently
27 paranoid callback functions.
29 1999-05-29 <tytso@rsts-11.mit.edu>
31 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
33 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
34 that we don't handle writing yet (we do). Fixed bug where
35 we weren't allocating a big enough buffer for ext2_bmap.
37 1999-05-03 <tytso@rsts-11.mit.edu>
39 * openfs.c (ext2fs_open): Check to make sure that the number of
40 blocks per group is not zero --- if so, it must be a bad
43 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
45 * Release of E2fsprogs 1.14
47 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
49 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
50 the inode number is zero; if it's zero, return
51 EXT2_ET_BAD_INODE_NUM.
53 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
55 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
56 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
59 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
61 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
62 non-Linux case to use EINVAL by default, unless it isn't
63 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
66 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
68 * Release of E2fsprogs 1.13
70 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
72 * Makefile.in: Updated dependencies.
74 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
76 * initialize.c (ext2fs_initialize): Make sure that we allocate
77 enough inodes so that we can make a valid filesystem.
79 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
81 * rw_bitmaps.c: Fixed signed/unsigned warnings.
83 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
86 * dblist.c (make_dblist): Add safety check in case the dblist
87 pointer passed in is null (in which case, assign it to
88 fs->dblist). Fixed some signed/unsigned warnings.
90 * bmap.c: Make addr_per_block be of type blk_t to avoid
91 signed/unsigned warnings.
93 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
96 * get_pathname.c (get_pathname_proc): Use return value from
97 ext2fs_get_mem, instead of checking if &gp->name is
100 * dir_iterate.c (ext2fs_process_dir_block):
101 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
102 from the function declaration.
104 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
105 return the error directly instead of jumping to the
106 cleanup routine, since we don't need to do any cleanup.
108 * alloc_table.c (ext2fs_allocate_group_table): Make this
109 function take a dgrp_t for its group argument.
111 * ext2fs.h: Make dgrp_t an __u32 type, and make
112 fs->desc_group_count be of type dgrp_t.
114 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
116 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
117 than 10 blocks when we need to expand the size of the
120 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
122 * Release of E2fsprogs 1.12
124 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
126 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
127 appropriate for all of the block group copies, so that
128 it's clear where the beginning of the filesystem is on the
129 disk. (For when the partition table gets scrod.)
131 * ext2fs.h: Change the name of the feature from
132 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
133 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
135 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
137 * inode.c (get_next_blockgroup): Fix bug where if
138 get_next_blockgroup() is called early because of a missing
139 inode table in a block group, the current_inode counter
140 wasn't incremented correctly.
142 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
144 * read_bb.c (ext2fs_read_bb_inode): Make function more robust
145 against a completely trashed bad block inode.
147 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
149 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
150 the stride length hits a bad value, we retry the block
151 allocation starting at the beginning of the block group.
153 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
154 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
155 e2_blkcnt_t to avoid collision with LFS API.
157 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
159 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
160 way that avoids overflows on disk sizes greater than 4GB.
162 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
164 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
165 return type for comparison functions for qsort.
167 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
170 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
172 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
175 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
176 evade a potential problem with glibc's header files trying
177 to spike out linux/types.h.
179 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
180 include the old size of the memory, which is needed for
181 some braindamaged memory allocation systems that don't
184 * badblocks.c (ext2fs_badblocks_list_add):
185 bb_inode.c (clear_bad_block_proc):

196 convention. Fix uninstall rules to take $(DESTDIR) into
199 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
201 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
202 with 32 bit longs, then we need to manually define __s64
203 and __u64, since the current kernel header files don't
204 define these if __STRICT_ANSI__ is defined. This is a
205 problem if we are compiling with full GCC warnings, since
206 we do need 64 bit support.
208 * Makefile.in (OBJS): Remove bmove.o from files to be built,
209 since we're not using ext2fs_move_blocks() and there
210 is some question as to its usefulness in its current
213 * bmap.c (block_bmap): Remove unused function.
215 * bmove.c (process_block): Fix -Wall warning.
217 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
219 * block.c (ext2fs_block_iterate3): Make the ref_offset field
220 contain the offset into the inode.i_blocks array when
221 ref_block is zero. Since we haven't done a formal
222 release of e2fsprogs since block_iterate2 was first
223 introduced, I removed block_iterate2, and renamed
224 block_iterate3 to be block_iterate2.
226 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
227 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
228 use of block_iterate and block_iterate2 to
229 block_iterate2 with the new prototype for the
230 interator function. (using blkcnt_t forr blockcount)
232 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
234 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
235 s_prealloc_blocks, s_prealloc_dir_blocks). Added
236 conditional defines of new features COMPAT_DIR_PREALLOC,
237 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
238 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
239 the library to declare that we support COMPAT_DIR_PREALLOC,
240 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
242 * fileio.c: Rename function ext2fs_file_llseek to be
243 ext2fs_file_lseek, which is more accurate.
245 * block.c: Add new function ext2fs_block_iterate3 which calls
246 the iterator function with the blockcount argument of
247 type blkcnt_t. This version of the function is
248 allowed to handle large files; the other fucntions are
251 * ext2fs.h: Add new type blkcnt_t
253 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
255 * block.c (ext2fs_block_iterate2): Fix bug where the block count
256 field wasn't getting correctly incremented for sparse
257 files when the indirect or doubly-indirect block
258 specified in the inode was zero.
260 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
262 * unlink.c (unlink_proc):
263 * lookup.c (lookup_proc):
264 * link.c (link_proc):
265 * get_pathname.c (get_pathname_proc):
266 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
267 from dirent->name_len, so it can be used for other
270 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
271 and indicate that we have support for this incompatible
274 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
276 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.
278 Fri Feb 20 23:58:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
280 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
281 number of directories when the block group information is
284 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
286 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
287 inode table is missing so that we catch the case where the
288 first block group is missing.
290 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
293 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
295 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
297 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
299 * test_io.c (test_flush): Add a debugging printf when the flush
302 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
303 read in, return right away.
305 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
307 * bitops.h: Don't try to do i386 inline asm functions if the
310 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
311 instead of linux/types.h, and e2_bitops.h instead of
314 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
317 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
319 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
320 so that we don't need to call get_next_blockgroup() the
321 first time around. Saves a bit of time, and prevents us
322 from needing to assign -1 to current_group (which is an
325 * icount.c (insert_icount_el): Cast the estimated number of inodes
326 from a float to an ino_t.
328 * alloc.c, alloc_tables.c, badlbocks.c, bb_compat.c, bb_inode.c,

338 tst_getsize.c, tst_iscan.c, unix_io.c, unlink.c,
339 valid_blk.c, version.c: If EXT2_FLAT_INCLUDES is
340 defined, then assume all of the
341 ext2-specific header files are in a flat directory.
343 * block.c, bmove.c, dirblock.c, fileio.c: Explicitly cast
344 all assignments from void * to be compatible with C++.

348 * closefs.c (ext2fs_flush): Add a call to io_channel_flush() to
349 make sure the contents of the disk are flushed to disk.
351 Mon Dec 29 14:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
353 * dblist.c (ext2fs_add_dir_block): Change new to be new_entry to
354 avoid C++ namespace clash.
356 * bitmaps.c (ext2fs_copy_bitmap): Change new to be new_map to
357 avoid C++ namespace clash.
359 * ext2fs.h, bb_inode.c, block.c, bmove.c, brel.h, brel_ma.c,
360 irel.h, irel_ma.c, dblist.c, dblist_dir.c, dir_iterate.c,
361 ext2fsP.h, expanddir.c, get_pathname.c, inode.c, link.c,
362 unlink.c: Change private to be priv_data (to avoid C++
365 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
367 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
368 paranoid about validating the directory counts from the
369 block group information.
371 * all files: Don't include stdlib.h anymore; include it in
372 ext2_fs.h, since that file requires stdlib.h
374 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
376 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
377 bitmap is loaded, and return an error if it is not.
378 (expand_dir_proc): Only use ext2fs_write_dir_block when
379 writing a directory block, not when writing out a fresh
382 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
384 * Makefile.in, tst_getsize.c: Added new file which is used to test

406 Sat Oct 25 00:06:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
408 * [all files, basically]: Added definition of ext2fs_get_mem,
409 ext2fs_free_mem, and ext2fs_resize_mem in ext2fs.h, and

430 * fileio.c: New file which implements simple file reading and
433 * alloc.c (ext2fs_alloc_block): New function which allocates a
434 block, zeros it, and updates the filesystem accounting
435 records appropriately.
437 Wed Oct 22 16:47:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
439 * ext2_err.et.in: Added new error codes: EXT2_NO_MEMORY,

464 Mon Sep 15 11:45:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
466 * inode.c (ext2fs_check_directory): Add support for the callback
467 to return the error code EXT2_ET_CALLBACK_NOTHANDLED.
469 Thu Sep 4 12:28:22 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
471 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
472 padding of the bitmap to be all one's.
474 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
476 * llseek.c: Added missing semicolon to glibc fixup declaration of
479 * bmove.c: Add #include of errno.h
481 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
483 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
484 added a new field to the io_channel (app_data).
486 * io.h: Add a new element to the io_channel structure, app_data.
488 * initialize.c, openfs.c: Set io->app_data to point at the
491 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
493 * io.h: Change the prototype of ext2fs_llseek() to use int's
494 instead of unsigned int's.
496 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
497 to make life easer for GNU Libc 2.
499 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
500 filesystem has its bitmaps stored as 32-bit words with bit
501 0 as the LSB of each word. Thus a bitmap with only bit 0
502 set would be, as a string of bytes, 00 00 00 01 00 ... To
503 cope with this, we byte-reverse each word of a bitmap if
504 we have a big-endian filesystem, that is, if we are *not*
505 byte-swapping other word-sized numbers.
507 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

530 * openfs.c (ext2fs_open):
531 * check_desc.c (ext2fs_check_desc): Use blk_t instead of int where
534 * rw_bitmaps.c (read_bitmaps):

574 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
576 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
577 is zero, then return EXT2_IO_LLSEEK_FAILED.
579 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
581 * Release of E2fsprogs 1.11

586 the number of directory blocks in dblist.
588 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
590 * unix_io.c (unix_flush): Make the io_channel flush function do a
591 fsync to flush the kernel buffers to disk.
593 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
595 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
596 current inode number wasn't being set by the
597 goto_blockgroup function.
599 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
601 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
602 of blocks which need to be moved, and moves those blocks
603 to another location in the filesystem.
605 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
606 bitmap, make sure all of the new parts of the bitmap are
609 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
611 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
612 wasn't being returned to the caller.
614 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
615 ext2fs_allocate_group_table() which sets the group tables
616 for a particular block group. The relevant code was
617 factored out of ext2fs_allocate_tables().
619 * dblist.c (make_dblist): Adjust the initial size of the directory
620 block list to be a bit more realistic (ten plus twice the
621 number of directories in the filesystem).
623 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
625 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
626 ext2fs_badblocks_list_test would test the list (and exceed
627 array boundaries) if there were no bad blocks on the bad
628 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
630 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
632 * Release of E2fsprogs version 1.10
634 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
636 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
637 inode and block bitmaps based on the RAID 0 stride
638 parameter (which is passed by mke2fs).
640 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
641 mke2fs to communicate the stride length to
642 ext2fs_allocate_tables()
644 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
646 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
647 systems. (We can't assume that the new filesystem types
650 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
652 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
653 allocate the inode and block bitmaps inside block group at
656 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
658 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the

662 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
664 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
665 free if refcount goes to zero.

681 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
683 (unix_close, test_close): Decrement the refcount and only
684 close the io_channel if the refcount goes to 0.
686 * io.h: Add refcount to the io_channel structure. Add new macro
687 interface io_channel_bumpcount() to bump the refcount.
689 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
691 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
692 cache in the filesystem handle, instead of the inode cache
693 in a static variable.
695 * freefs.c: Added static function to free the inode cache (called by
698 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
700 * ext2fs.h: Added pointer to the inode_cache structure.
702 * block.c (block_iterate_ind, block_iterate_dind,
703 block_iterate_tind): If there are holes in the indirect,
704 doubly indirect, or triply indirect blocks, increment the
705 block count field automatically.
707 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
709 * Release of E2fsprogs version 1.09
711 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
713 * version.c (ext2fs_parse_version_string): Check the passed in
714 version string (instead of the hard-coded one).
716 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
717 greater filesystem size, clamp it to prevent allocating a
718 block or inode bitmap beyond the filesystem.
720 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
721 overhead calculation was accidentally removed.
723 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
725 * Release of E2fsprogs version 1.08
727 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
729 * dblist.c (ext2fs_set_dir_block): New function which sets the
730 block of a dblist entry, given the directory inode and
733 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
735 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
736 inode bitmaps at staggered locations across the block
737 groups, to avoid concentrating the bitmaps on a small
738 number of disks when using striped RAID arrays.
740 * initialize.c (ext2fs_initialize): By default, choose the maximum
741 possible number of blocks per group (based on the size of
742 the bitmaps in the blocksize).
744 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
746 * initialize.c (ext2fs_initialize): Add support for
747 EXT2_COMPAT_SPARSE_SUPER feature.
749 * closefs.c (ext2fs_bg_has_super): New function to determine
750 whether or a particular block group should have a
751 superblock and block group descriptor. Used for the
752 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
753 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
754 or not the superblock should be written out for the block
757 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
758 for sparse duplicate superblocks.
760 * version.c (ext2fs_get_library_version): New function which
761 returns the library version.
763 * version.c (ext2fs_parse_version_string): New function which
764 parses a version string and returns a version number,
765 so application programs can compare version numbers as
768 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * icount.c (ext2fs_create_icount): Change function so that it also
771 takes a new argument which contains a "hint" icount
772 structure. This "hint" icount allows the create function
773 to set up the sorted list in advance. This reduces
774 significantly the amount of data moving needed to insert
775 these inodes into the list later.
777 * icount.c (ext2fs_icount_validate): New function which validates
778 that the icount structure's rep invariant.
780 * icount.c (get_icount_el): Completely revamped implementation
781 to subsume put_icount_el(). Put_icount_el() used to
782 use an O(N) implementation to insert in the middle
783 of the icount list. It now uses a O(ln N) to search
784 for where the icount should be inserted, and then uses
785 a memcpy to move the list down (instead of a for loop).
787 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
788 ext2fs_icount_increment, ext2fs_icount_decrement): Check
789 to see if the inode is within bounds; if it isn't, return
792 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
793 when a bad inode number is passed to test_generic_bitmap
794 to be EXT2FS_TEST_ERROR instead of the wrong
797 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
799 * Release of E2fsprogs version 1.07
801 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
803 * Makefile.in (ELF_VERSION): Change version to be 2.2
805 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
807 * alloc.c (ext2fs_get_free_blocks): Change routine to use
808 ext2fs_fast_test_block_bitmap_range().
810 * bitops.h (ext2fs_fast_test_block_bitmap_range,
811 ext2fs_test_block_bitmap_range: New inline functions which
812 test to see whether a contiguous range of blocks is
815 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
817 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
818 use ext2fs_badblocks_* instead of badblocks_*
820 * bb_compat.c: New file which translates between old badblocks_*()
821 names to ext2fs_badblocks_*()
823 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
824 link.c (since e2fsck doesn't use ext2fs_unlink()).
826 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
827 bitmap resizing routine moved from bitmaps.c, since e2fsck
828 doesn't need to use this function.
830 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
831 since e2fsck only needs ext2fs_lookup.
833 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
835 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
836 already set; this is needed so that programs like dump
837 which use the inode scan functions will deal with
838 filesystems that have bad blocks in the inode table.
840 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
842 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
843 Moved to ext2fsP.h, since it doesn't need to be part of
844 the public interface.
846 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
848 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
850 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
851 directory block list abstraction. (Code moved from
854 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
855 to inode.c (since no one else should be peeking inside it!)
857 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
859 * openfs.c (ext2fs_open): Check the feature set in the ext2
860 superblock, and refuse to open filesystems if they contain
861 incompatible features. (Can be overriden with the
864 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
866 * block.c (ext2fs_block_iterate2): Added new function
867 ext2fs_block_iterate2 which changes the function
868 signature of the callback function to include the
869 referencing block and offset.
871 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
872 ext2fs_inode_scan_goto_blockgroup which allows an
873 application to jump to a particular block group while
876 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
878 * dirblock.c: Include string.h, since we use memcpy().
880 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
882 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
883 a long not an int; this doesn't matter on i386 machines,
884 but it does on Alpha's.
886 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
888 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
889 table pointer is NULL, then return an error indicating
890 that the inode table is missing.
891 (get_next_blockgroup, get_next_blocks,
892 ext2fs_get_next_inode): Don't treat a missing inode table
893 as permanent error. Return MISSING_INODE_TABLE, but as an
894 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
896 * rw_bitmaps.c (ext2fs_write_block_bitmap,
897 ext2fs_write_inode_bitmap): If the inode or block bitmap
898 block is zero, then don't write out the inode or block
899 bitmap. The idea here is to avoid stomping on the
901 (read_bitmaps): If the inode or block bitmap block is
902 zero, then fill in that portion of the inode or block
903 bitmap with all zeros.
905 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
906 blocks in inode table when the inode table size is
907 non-standard (and can therefore span blocks).
909 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
911 * alloc.c (ext2fs_new_block): Fix fencepost error in
912 ext2fs_new_block; make sure we don't try to allocate the
913 first block beyond the end of the filesystem.
915 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
917 * inode.c (check_for_inode_bad_blocks): New function called by
918 get_next_blocks() to avoid reading in bad blocks marked in
919 fs->badblocks. Inodes located in bad blocks are returned
920 by ext2fs_get_next_inode() returns the error code
921 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
923 * alloc_tables.c (ext2fs_allocate_tables): New function which
924 performs the part of mke2fs's job of allocating the
927 * test_io.c (test_close): IO manager which is used for testing
930 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
932 * inode.c (ext2fs_get_next_inode): Separate out the function of
933 setting up for a new block group to get_next_blockgroup().
934 Separate out the function of reading in blocks of the
935 inode table to get_next_blocks().
937 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
939 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
940 blocks to the badblock list in sorted order. This allows
941 badblocks_list_test to be coded using a binary search for
944 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
946 * Release of E2fsprogs version 1.06
948 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
950 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
951 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
954 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
955 set, then only write out the master superblock.
957 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
959 * block.c (ext2fs_block_iterate): Fixed bug which caused
960 block_iterate to fail to handle HURD created filesystems;
961 it tested the inode translator field before the inode was
964 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
966 * initialize.c (ext2fs_initialize): Make sure the description for
967 the inode bitmap is set correctly.
969 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
971 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
973 * Release of E2fsprogs version 1.05
975 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
977 * initialize.c: Override the kernel's idea of default
978 checkinterval from 0 (never) to 180 days.

992 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
995 * namei.c (ext2fs_follow_link): New function.
996 (ext2fs_namei): Extended to have support for chasing
997 symbolic links. ext2fs_namei() still returns an inode
998 which is a symbolic link. Symbolic links are only chased
999 while resolving the containing directory. To chase
1000 symbolic links of the final result, use
1001 ext2fs_follow_link().
1003 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1005 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1007 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1008 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
1010 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1012 * initialize.c (ext2fs_initialize): On systems where the byte
1013 order is not i386 compatible, set the swap_byte flag.
1015 * inode.c (inocpy_with_swap): Check to see if inode contains a
1016 fast symlink before swapping the inode block fields. This
1017 required adding a new argument to inocpy_with_swap to
1018 determine whether the mode field is in host order or not.
1020 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1022 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1023 the sparc, if EXT2_STD_BITOPS set, use the standard
1024 i386-compatible bitmask operations, instead on the
1025 non-standard native bitmask operators.
1027 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1029 * block.c (ext2fs_block_iterate): Cause block iterator to return
1030 the HURD translator block (along with everything else).
1031 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
1032 iterator, then don't return any meta data blocks
1033 (including the HURD translator).
1035 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1037 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1039 * uuid.c: New file, containing UUID utility functions.
1041 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1043 * ext2fs.h: Add a definition of the "real" ext2 superblock.
1045 Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1047 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
1049 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1051 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1052 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1053 that's a basic value that must be correct for the rest of
1054 the library to work.
1056 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1059 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1061 * Release of E2fsprogs version 1.04

1134 * Makefile.in: Added support for BSD shared libraries.
1136 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1139 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1141 * unix_io.c (unix_open): Add a double check; if the passed in name

1168 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1169 Move these functions to freefs.c.
1171 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1172 descriptors shadow memory to keep purify quiet. (This
1173 also has the nice benefit that the unused portion of the
1174 shadow descriptors are zeroed out.)
1176 * dirblock.c (ext2fs_write_dir_block): We need to use
1177 dirent->rec_len *before* it's byteswapped to find the
1178 location of the next directory structure!
1180 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1181 cause ext2fs_new_inode to loop infinitely if we're trying
1182 to allocate an inode in group #0 and there are no free
1183 inodes at all in the system.
1185 * closefs.c: #include <errno.h> if it exists.
1187 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1189 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1206 file containing functions for reading and writing
1207 directory blocks (byte swapping if necesssary)
1209 * block.c (block_iterate_ind, block_iterate_dind,
1210 block_iterate_tind): Byte swap the block addresses if
1211 EXT2_SWAP_BYTES is set (and swap them back before writing
1214 * inode.c (inocpy_with_swap): New function.
1215 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1216 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1218 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1219 the superblock and group descriptors before writing it out.
1221 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1222 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1223 and group descriptors.
1225 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1226 to desp ext2 filesystem structures.
1228 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1229 supplied by Pete A. Zaitcev so that the C language
1230 versions of these functions are more portable. They will
1231 now work on both little and big endian systems, and the
1232 assumption that 32-bit integers are used is gone.
1234 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1235 doing byte swapping.
1237 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1238 byte swapping should take place.
1240 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1251 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1252 if the magic number is correct, it will be allocated.
1254 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1256 * block.c (block_iterate_ind, block_iterate_dind,
1257 block_iterate_tind): Don't recompute block_nr each loop;
1258 just increment it! Factor check of BLOCK_FLAG_APPEND out
1259 of the loop. Factor mask of BLOCK_CHANGED into changed
1260 variable out of the loop. (block_iterate_ind, in
1261 particular, gets called a lot, so every little
1262 optimization helps.)
1264 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1266 * block.c (block_iterate_ind, block_iterate_dind,

1268 block_iterate_ind and company.
1270 * bitops.h (ext2fs_fast_mark_block_bitmap,
1271 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1272 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1273 ext2fs_fast_test_inode_bitmap): Add fast version of these
1274 functions, which don't do range checking.
1276 * bitops.h (ext2fs_get_block_bitmap_start,
1277 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1278 ext2fs_get_inode_bitmap_end): Add new accessor functions
1279 which return the start and end points of the bitmaps.
1281 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1283 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1284 instead of llseek. The errno if the offset is too large
1285 and lseek is not supported should be EINVAL, not -EINVAL.
1287 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1289 * Makefile.in: Added support for ELF shared libraries.
1290 Fixed typos in the compilation rules.
1291 (distclean): Added Makefile.
1293 * llseek.c (llseek): New function, if llseek() does not exist in the
1295 (ext2_llseek): Changed to call llseek().
1297 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1299 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1301 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1303 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1305 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1306 the S_*, which are normally defined in <sys/stat.h>. This
1307 allows us to compile e2fsprogs on a non-Linux system,
1308 which may have a different value for S_IFDIR.
1310 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1312 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1313 this is a user-mode application!
1315 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1317 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1318 __linux__ so that non-linux systems won't see it.
1320 * alloc.c: Include <errno.h> if possible.
1321 * badblocks.c: Ditto.
1322 * bb_inode.c: Ditto.
1325 * expanddir.c: Ditto.
1326 * get_pathname.c: Ditto.
1327 * initialize.c: Ditto.
1334 * rw_bitmaps.c: Ditto.
1337 * Makefile.in: Rewritten to conform to GNU coding standards and
1338 support separate compilation directories.
1340 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1342 * initialize.c (ext2fs_initialize): Don't allow more than one
1343 bitmaps's worth of inodes in a group.
1345 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1347 * llseek.c (ext2_llseek): Added error checking to the llseek()
1348 compat code to protect against overflow. This only
1349 applies to 1.0 and early 1.1 kernels, which don't support
1350 the llseek() system call.
1352 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1354 * unix_io.c (unix_open): Initialize the read_error and write_error
1355 io_channel pointers to be null.
1357 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1358 found, clear it but don't try to update the filesystem
1359 accounting information, since that's hopeless anyway.
1361 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1362 bloblock_iterate_tind): Check to see if the indirect blocks are
1363 valid before trying to read them.

1366 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1368 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1369 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1370 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1371 illegal block or inode number is passed in, return instead
1372 of trying to test, set, or clear the bit.
1374 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1376 * Makefile: Added a dummy install target in case shared libraries
1379 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1381 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how

1386 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1387 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1388 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1389 ext2fs_free_block_bitmap): Add magic number checking for
1390 the inode and block bitmaps.
1392 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1393 magic number for a block bitmap instead of an inode bitmap.
1395 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1396 magic number checking for the inode_scan structure.

1399 badblocks_list_test, badblocks_list_iterate_begin,
1400 badblocks_list_iterate, badblocks_list_iterate_end): Add
1401 magic number checking for the badblocks_list and
1402 badblocks_iterate structures.
1404 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1405 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1406 unix_write_blk, unix_flush): Add magic number checking
1407 both for io_channel structure and unix_private_data
1410 * openfs.c (ext2fs_open): Add check for io_manager structure's
1413 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1414 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1415 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1416 * read_bb.c (ext2fs_read_bb_inode):
1417 * read_bb_file.c (ext2fs_read_bb_FILE):

1428 ext2fs_allocate_block_bitmap):
1429 * bb_inode.c (ext2fs_update_bb_inode):
1430 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

1432 * closefs.c (ext2fs_close, ext2fs_flush):
1433 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1438 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1439 openfs.c into its own file.
1441 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1442 structure magic numbers.
1444 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1445 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1446 someone uses the -b option to specify the use of the backup
1447 superblock --- this usually means that the main superblock is
1451 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1452 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1453 revision level to the superblock.
1455 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1462 * initialize.c: Completely revamped the inode and block bitmap
1463 structures, so that they can be better chance of being extensible
1464 in a shared library. They are now their own type, instead of
1465 being a char *. Also, the function signatures of
1466 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1467 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1468 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1469 changed to eliminate the ext2_filsys argument, since it is no
1472 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1474 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1475 system call if available.
1477 * llseek.c: new file. This is the stub calling the llseek system
1478 call which allows supports for 2GB+ file systems.
1480 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1481 the creator operating system.
1483 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1485 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1486 the group descriptor statistics in addition to everything else.
1487 This relieves mke2fs of the responsibility of doing it.
1489 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1490 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1491 not the generic C function equivalents should be included or not.
1493 * openfs.c (ext2fs_open): If a superblock is specified, then use
1494 the backup group descriptors that go along with this superblock,
1495 instead of using the primary group descriptors. This allows
1496 e2fsck to recover filesystems where the primary group descriptors
