1 1999-11-08 <tytso@valinux.com>
3 * Makefile.in (tst_badblocks): Add freefs.o to the object list,
4 since ext2fs_badblocks_list_free was moved to freefs.c.
6 * tst_badblocks.c: Use the newer badblocks API names. Add
7 duplicate blocks to the test inputs to test dealing with
8 adding blocks which are already in the badblocks list.
10 * badblocks.c (ext2fs_badblocks_list_add): If appending to the end
11 of the list, use a shortcut O(1) operations instead of an
12 O(n) operation. (Idea suggested by David Beattie.)
14 * freefs.c (ext2fs_free): Use ext2fs_badblocks_list_free() instead
15 of badblocks_list_free(), to save a procedure call.
17 1999-10-26 <tytso@valinux.com>
19 * Release of E2fsprogs 1.17
21 1999-10-26 <tytso@valinux.com>
23 * ext2fs.h: Add kludge to deal with the fact that egcs cpp doesn't
24 seem to handle ~0UL the same way as they used to.
26 1999-10-25 <tytso@valinux.com>
28 * nt_io.c (_OpenNtName): Open the device using
29 FILE_SYNCHRONOUS_IO_NONALERT instead of
30 FILE_SYNCHRONOUS_IO_ALERT
31 (nt_open): At the end of the device open routine, unlock
32 the drive but do not dismount it.
34 * initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to
37 1999-10-22 <tytso@valinux.com>
39 * Release of E2fsprogs 1.16
41 1999-10-22 <tytso@valinux.com>
43 * mkdir.c (ext2fs_mkdir): Pass EXT2_FT_DIR flag to ext2fs_link().
45 * link.c (ext2fs_link): This call now uses the low three bits of
46 the flags parameter to pass the directory filetype
47 information; it will set the directory entry FILETYPE
48 information if the filesystem supports it.
50 * newdir.c (ext2fs_new_dir_block): If the FILETYPE superblock
51 option is set, then create the '.' and '..' entries with
52 the filetype set to EXT2_FT_DIR.
54 1999-09-24 <tytso@valinux.com>
56 * nt_io.c: New file which supports I/O under Windows NT.
58 1999-09-07 <tytso@valinux.com>
60 * ext2fs.h: Add new fields for journalling and define new
61 feature bits used by newer filesystems: IMAGIC_INODES,
64 * expanddir.c (ext2fs_expand_dir, expand_dir_proc): Change where
65 we update the inode block count and size files so that the
66 block count field is updated correctly when we create an
69 1999-07-18 Theodore Ts'o <tytso@valinux.com>
71 * Release of E2fsprogs 1.15
73 1999-06-23 <tytso@valinux.com>
75 * swapfs.c (ext2fs_swap_inode): Add compatibility for Linux 2.3
76 kernels that use i_generation instead of i_version. Patch
77 supplied by Jon Bright <sircus@sircus.demon.co.uk>.
79 1999-06-21 <tytso@valinux.com>
81 * dir_iterate.c (ext2fs_process_dir_block): Check for corrupted
82 directory entry before calling the callback function.
83 This should prevent some core dumps of insufficiently
84 paranoid callback functions.
86 1999-05-29 <tytso@rsts-11.mit.edu>
88 * ext2fs.h: Add feature definition for AFS IMAGIC inodes.
90 * fileio.c (ext2fs_file_open): Remove obsolete comment stating
91 that we don't handle writing yet (we do). Fixed bug where
92 we weren't allocating a big enough buffer for ext2_bmap.
94 1999-05-03 <tytso@rsts-11.mit.edu>
96 * openfs.c (ext2fs_open): Check to make sure that the number of
97 blocks per group is not zero --- if so, it must be a bad
100 1999-01-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
102 * Release of E2fsprogs 1.14
104 1999-01-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
106 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Check to see if
107 the inode number is zero; if it's zero, return
108 EXT2_ET_BAD_INODE_NUM.
110 1998-12-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
112 * initialize.c (ext2fs_initialize): Use EXT2_FIRST_INODE instead
113 of EXT2_FIRST_INO to ensure compatibility with Linux 1.2
116 Mon Jan 4 02:32:09 1999 Theodore Y. Ts'o <tytso@mit.edu>
118 * llseek.c (ext2fs_llseek): Change ext2fs_llseek() in the
119 non-Linux case to use EINVAL by default, unless it isn't
120 defined, in which case we use EXT2_ET_INVALID_ARGUMENT
123 1998-12-15 Theodore Ts'o <tytso@rsts-11.mit.edu>
125 * Release of E2fsprogs 1.13
127 1998-12-03 Theodore Ts'o <tytso@rsts-11.mit.edu>
129 * Makefile.in: Updated dependencies.
131 1998-09-22 Theodore Ts'o <tytso@rsts-11.mit.edu>
133 * initialize.c (ext2fs_initialize): Make sure that we allocate
134 enough inodes so that we can make a valid filesystem.
136 1998-09-02 Theodore Ts'o <tytso@rsts-11.mit.edu>
138 * rw_bitmaps.c: Fixed signed/unsigned warnings.
140 * fileio.c (ext2fs_file_set_size): Remove unneeded extern from the
141 function declaration.
143 * dblist.c (make_dblist): Add safety check in case the dblist
144 pointer passed in is null (in which case, assign it to
145 fs->dblist). Fixed some signed/unsigned warnings.
147 * bmap.c: Make addr_per_block be of type blk_t to avoid
148 signed/unsigned warnings.
150 * namei.c (ext2fs_follow_link): Remove uneeded extern from the
151 function declaration.
153 * get_pathname.c (get_pathname_proc): Use return value from
154 ext2fs_get_mem, instead of checking if &gp->name is

158 * dblist_dir.c (ext2fs_dblist_dir_iterate): Remove uneeded extern
159 from the function declaration.
161 * block.c (ext2fs_block_iterate2): If the read_inode call fails,
162 return the error directly instead of jumping to the
163 cleanup routine, since we don't need to do any cleanup.
165 * alloc_table.c (ext2fs_allocate_group_table): Make this
166 function take a dgrp_t for its group argument.
168 * ext2fs.h: Make dgrp_t an __u32 type, and make
169 fs->desc_group_count be of type dgrp_t.
171 1998-07-27 Theodore Ts'o <tytso@rsts-11.mit.edu>
173 * badblocks.c (ext2fs_badblocks_list_add): Use a bigger increment
174 than 10 blocks when we need to expand the size of the
177 1998-07-09 Theodore Ts'o <tytso@rsts-11.mit.edu>
179 * Release of E2fsprogs 1.12
181 1998-06-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
183 * closefs.c (ext2fs_flush): Update the s_block_group_nr field as
184 appropriate for all of the block group copies, so that
185 it's clear where the beginning of the filesystem is on the
186 disk. (For when the partition table gets scrod.)
188 * ext2fs.h: Change the name of the feature from
189 EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to
190 EXT2_FEATURE_INCOMPAT_FILESIZE (to match with the kernel).
192 1998-06-18 Theodore Ts'o <tytso@rsts-11.mit.edu>
194 * inode.c (get_next_blockgroup): Fix bug where if
195 get_next_blockgroup() is called early because of a missing
196 inode table in a block group, the current_inode counter
197 wasn't incremented correctly.
199 1998-06-16 Theodore Ts'o <tytso@rsts-11.mit.edu>
201 * read_bb.c (ext2fs_read_bb_inode): Make function more robust

204 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
206 * alloc_tables.c (ext2fs_allocate_group_table): Fix bug so that if
207 the stride length hits a bad value, we retry the block
208 allocation starting at the beginning of the block group.
210 * ext2fs.h, bb_inode.c, block.c, bmove.c, dir_iterate.c,
211 expanddir.c, ext2fsP.h, read_bb.c: Change blkcnt_t to be
212 e2_blkcnt_t to avoid collision with LFS API.
214 1998-05-01 Theodore Ts'o <tytso@rsts-11.mit.edu>
216 * initialize.c (ext2fs_initialize): Initialize s_inodes_count in a
217 way that avoids overflows on disk sizes greater than 4GB.
219 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
221 * ext2fs.h: Define EXT2_QSORT_TYPE appropriately for the
222 return type for comparison functions for qsort.
224 * dblist.c (dir_block_cmp): Use EXT2_QSORT_TYPE in function
227 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
229 * ext2fs.h, bitops.h: Add support for the Watcom C compiler to do
232 * ext2fs.h, dosio.c: Use asm/types.h instead of linux/types.h to
233 evade a potential problem with glibc's header files trying
234 to spike out linux/types.h.
236 * ext2fs.h (ext2fs_resize_mem): Change the function prototype to
237 include the old size of the memory, which is needed for
238 some braindamaged memory allocation systems that don't
241 * badblocks.c (ext2fs_badblocks_list_add):
242 bb_inode.c (clear_bad_block_proc):

253 convention. Fix uninstall rules to take $(DESTDIR) into
256 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
258 * ext2fs.h: If __STRICT_ANSI__ is defined and we're on a platform
259 with 32 bit longs, then we need to manually define __s64
260 and __u64, since the current kernel header files don't
261 define these if __STRICT_ANSI__ is defined. This is a
262 problem if we are compiling with full GCC warnings, since
263 we do need 64 bit support.
265 * Makefile.in (OBJS): Remove bmove.o from files to be built,
266 since we're not using ext2fs_move_blocks() and there
267 is some question as to its usefulness in its current
270 * bmap.c (block_bmap): Remove unused function.
272 * bmove.c (process_block): Fix -Wall warning.
274 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
276 * block.c (ext2fs_block_iterate3): Make the ref_offset field
277 contain the offset into the inode.i_blocks array when
278 ref_block is zero. Since we haven't done a formal
279 release of e2fsprogs since block_iterate2 was first
280 introduced, I removed block_iterate2, and renamed
281 block_iterate3 to be block_iterate2.
283 * bb_inode.c, bmove.c, dblist_dir.c, dir_iterate.c,
284 expanddir.c, ext2fs.h, ext2fsP.h, read_bb.c: Change
285 use of block_iterate and block_iterate2 to
286 block_iterate2 with the new prototype for the
287 interator function. (using blkcnt_t forr blockcount)
289 1998-03-21 Theodore Ts'o <tytso@rsts-11.mit.edu>
291 * ext2fs.h: Add new superblock fields (s_algorithm_usage_bitmap,
292 s_prealloc_blocks, s_prealloc_dir_blocks). Added
293 conditional defines of new features COMPAT_DIR_PREALLOC,
294 RO_COMPAT_LARGE_FILE RO_COMPAT_BTREE_DIR,
295 INCOMPAT_COMPRESSION, INCOMPAT_DIRNAME_SIZE. Changed
296 the library to declare that we support COMPAT_DIR_PREALLOC,
297 INCOMPAT_DIRNAME_SIZE, RO_COMPAT_LARGE_FILE.
299 * fileio.c: Rename function ext2fs_file_llseek to be
300 ext2fs_file_lseek, which is more accurate.
302 * block.c: Add new function ext2fs_block_iterate3 which calls
303 the iterator function with the blockcount argument of
304 type blkcnt_t. This version of the function is
305 allowed to handle large files; the other fucntions are
308 * ext2fs.h: Add new type blkcnt_t
310 * ext2_err.et.in: Add error code EXT2_ET_FILE_TOO_BIG
312 * block.c (ext2fs_block_iterate2): Fix bug where the block count
313 field wasn't getting correctly incremented for sparse
314 files when the indirect or doubly-indirect block
315 specified in the inode was zero.
317 Sun Mar 8 22:42:47 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
319 * unlink.c (unlink_proc):
320 * lookup.c (lookup_proc):
321 * link.c (link_proc):
322 * get_pathname.c (get_pathname_proc):
323 * dir_iterate.c (ext2fs_process_dir_block): Mask off high 8 bits
324 from dirent->name_len, so it can be used for other
327 * ext2fs.h: Add definition of EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE,
328 and indicate that we have support for this incompatible
331 Mon Feb 23 08:46:33 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
333 * ext2_err.et.in: Added new error code, EXT2_ET_CANCEL_REQUESTED.

337 * dblist.c (ext2fs_get_num_dirs): Improve the estimation of the
338 number of directories when the block group information is
341 1998-02-20 Theodore Y. Ts'o <tytso@edt.mit.edu>
343 * inode.c (ext2fs_get_next_inode): Always do the check to see if the
344 inode table is missing so that we catch the case where the
345 first block group is missing.
347 * getsize.c, ismounted.c, unix_io.c: #include errno.h since it's
350 Mon Feb 16 16:16:00 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
352 * ext2_io.h, ext2fs.h: Protect against being included multiple times.
354 * bmove.c: #include ext2fsP.h instead of "ext2fs/ext2fs.h"
356 * test_io.c (test_flush): Add a debugging printf when the flush
359 * rw_bitmaps.c (ext2fs_read_bitmaps): If the bitmaps are already
360 read in, return right away.
362 Sun Feb 1 08:20:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
364 * bitops.h: Don't try to do i386 inline asm functions if the
367 * ext2fs.h: If EXT2_FLAT_INCLUDES is defined, #include e2_types.h,
368 instead of linux/types.h, and e2_bitops.h instead of
371 * icount.c, version.c: Don't #include <et/com_err.h>, as it isn't
374 Sat Jan 17 13:13:31 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
376 * inode.c (ext2fs_open_inode_scan): Initialize the group variables
377 so that we don't need to call get_next_blockgroup() the
378 first time around. Saves a bit of time, and prevents us
379 from needing to assign -1 to current_group (which is an
382 * icount.c (insert_icount_el): Cast the estimated number of inodes
383 from a float to an ino_t.

422 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
424 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
425 paranoid about validating the directory counts from the
426 block group information.
428 * all files: Don't include stdlib.h anymore; include it in
429 ext2_fs.h, since that file requires stdlib.h
431 Thu Nov 20 16:07:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
433 * expanddir.c (ext2fs_expand_dir): Check to make sure the block
434 bitmap is loaded, and return an error if it is not.
435 (expand_dir_proc): Only use ext2fs_write_dir_block when
436 writing a directory block, not when writing out a fresh
439 Tue Nov 11 22:46:45 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
441 * Makefile.in, tst_getsize.c: Added new file which is used to test

528 * bitmaps.c (ext2fs_set_bitmap_padding): New function which sets the
529 padding of the bitmap to be all one's.
531 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
533 * llseek.c: Added missing semicolon to glibc fixup declaration of
536 * bmove.c: Add #include of errno.h
538 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
540 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
541 added a new field to the io_channel (app_data).

550 * io.h: Change the prototype of ext2fs_llseek() to use int's
551 instead of unsigned int's.
553 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
554 to make life easer for GNU Libc 2.
556 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
557 filesystem has its bitmaps stored as 32-bit words with bit
558 0 as the LSB of each word. Thus a bitmap with only bit 0
559 set would be, as a string of bytes, 00 00 00 01 00 ... To
560 cope with this, we byte-reverse each word of a bitmap if
561 we have a big-endian filesystem, that is, if we are *not*
562 byte-swapping other word-sized numbers.
564 Mon Aug 11 03:30:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

631 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
633 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
634 is zero, then return EXT2_IO_LLSEEK_FAILED.
636 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
638 * Release of E2fsprogs 1.11
640 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
642 * dblist.c (ext2fs_dblist_count): Added new function which returns
643 the number of directory blocks in dblist.
645 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
647 * unix_io.c (unix_flush): Make the io_channel flush function do a
648 fsync to flush the kernel buffers to disk.
650 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
652 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
653 current inode number wasn't being set by the
654 goto_blockgroup function.
656 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
658 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
659 of blocks which need to be moved, and moves those blocks
660 to another location in the filesystem.
662 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
663 bitmap, make sure all of the new parts of the bitmap are
666 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
668 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
669 wasn't being returned to the caller.
671 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
672 ext2fs_allocate_group_table() which sets the group tables
673 for a particular block group. The relevant code was
674 factored out of ext2fs_allocate_tables().
676 * dblist.c (make_dblist): Adjust the initial size of the directory
677 block list to be a bit more realistic (ten plus twice the
678 number of directories in the filesystem).
680 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
682 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
683 ext2fs_badblocks_list_test would test the list (and exceed
684 array boundaries) if there were no bad blocks on the bad
685 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
687 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
689 * Release of E2fsprogs version 1.10
691 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
693 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
694 inode and block bitmaps based on the RAID 0 stride
695 parameter (which is passed by mke2fs).
697 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
698 mke2fs to communicate the stride length to
699 ext2fs_allocate_tables()
701 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
703 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
704 systems. (We can't assume that the new filesystem types
707 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
709 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
710 allocate the inode and block bitmaps inside block group at

715 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
716 filesystem has no free blocks, ext2fs_new_block would loop
719 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
721 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
722 free if refcount goes to zero.
724 * inode.c (create_icache): Initialize refcount to 1.
726 * ext2fsP.h: Added refcount to ext2_inode_cache
728 * dblist.c (ext2fs_copy_dblist): New function to copy a directory

738 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
740 (unix_close, test_close): Decrement the refcount and only
741 close the io_channel if the refcount goes to 0.
743 * io.h: Add refcount to the io_channel structure. Add new macro
744 interface io_channel_bumpcount() to bump the refcount.
746 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
748 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
749 cache in the filesystem handle, instead of the inode cache
750 in a static variable.
752 * freefs.c: Added static function to free the inode cache (called by
755 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
757 * ext2fs.h: Added pointer to the inode_cache structure.
759 * block.c (block_iterate_ind, block_iterate_dind,
760 block_iterate_tind): If there are holes in the indirect,
761 doubly indirect, or triply indirect blocks, increment the
762 block count field automatically.
764 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
766 * Release of E2fsprogs version 1.09
768 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
770 * version.c (ext2fs_parse_version_string): Check the passed in
771 version string (instead of the hard-coded one).
773 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
774 greater filesystem size, clamp it to prevent allocating a
775 block or inode bitmap beyond the filesystem.
777 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
778 overhead calculation was accidentally removed.
780 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
782 * Release of E2fsprogs version 1.08
784 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
786 * dblist.c (ext2fs_set_dir_block): New function which sets the
787 block of a dblist entry, given the directory inode and
790 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
792 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
793 inode bitmaps at staggered locations across the block
794 groups, to avoid concentrating the bitmaps on a small
795 number of disks when using striped RAID arrays.
797 * initialize.c (ext2fs_initialize): By default, choose the maximum
798 possible number of blocks per group (based on the size of
799 the bitmaps in the blocksize).
801 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
803 * initialize.c (ext2fs_initialize): Add support for
804 EXT2_COMPAT_SPARSE_SUPER feature.
806 * closefs.c (ext2fs_bg_has_super): New function to determine
807 whether or a particular block group should have a
808 superblock and block group descriptor. Used for the
809 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
810 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
811 or not the superblock should be written out for the block
814 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
815 for sparse duplicate superblocks.
817 * version.c (ext2fs_get_library_version): New function which
818 returns the library version.
820 * version.c (ext2fs_parse_version_string): New function which
821 parses a version string and returns a version number,
822 so application programs can compare version numbers as
825 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
827 * icount.c (ext2fs_create_icount): Change function so that it also
828 takes a new argument which contains a "hint" icount
829 structure. This "hint" icount allows the create function
830 to set up the sorted list in advance. This reduces
831 significantly the amount of data moving needed to insert
832 these inodes into the list later.
834 * icount.c (ext2fs_icount_validate): New function which validates
835 that the icount structure's rep invariant.
837 * icount.c (get_icount_el): Completely revamped implementation
838 to subsume put_icount_el(). Put_icount_el() used to
839 use an O(N) implementation to insert in the middle
840 of the icount list. It now uses a O(ln N) to search
841 for where the icount should be inserted, and then uses
842 a memcpy to move the list down (instead of a for loop).
844 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
845 ext2fs_icount_increment, ext2fs_icount_decrement): Check
846 to see if the inode is within bounds; if it isn't, return
849 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
850 when a bad inode number is passed to test_generic_bitmap
851 to be EXT2FS_TEST_ERROR instead of the wrong
854 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
856 * Release of E2fsprogs version 1.07
858 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
860 * Makefile.in (ELF_VERSION): Change version to be 2.2
862 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
864 * alloc.c (ext2fs_get_free_blocks): Change routine to use
865 ext2fs_fast_test_block_bitmap_range().
867 * bitops.h (ext2fs_fast_test_block_bitmap_range,
868 ext2fs_test_block_bitmap_range: New inline functions which
869 test to see whether a contiguous range of blocks is
872 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
874 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
875 use ext2fs_badblocks_* instead of badblocks_*
877 * bb_compat.c: New file which translates between old badblocks_*()
878 names to ext2fs_badblocks_*()
880 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
881 link.c (since e2fsck doesn't use ext2fs_unlink()).
883 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
884 bitmap resizing routine moved from bitmaps.c, since e2fsck
885 doesn't need to use this function.
887 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
888 since e2fsck only needs ext2fs_lookup.
890 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
892 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
893 already set; this is needed so that programs like dump
894 which use the inode scan functions will deal with
895 filesystems that have bad blocks in the inode table.
897 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
899 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
900 Moved to ext2fsP.h, since it doesn't need to be part of
901 the public interface.
903 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
905 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
907 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
908 directory block list abstraction. (Code moved from
911 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
912 to inode.c (since no one else should be peeking inside it!)
914 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
916 * openfs.c (ext2fs_open): Check the feature set in the ext2
917 superblock, and refuse to open filesystems if they contain
918 incompatible features. (Can be overriden with the
921 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
923 * block.c (ext2fs_block_iterate2): Added new function
924 ext2fs_block_iterate2 which changes the function
925 signature of the callback function to include the
926 referencing block and offset.
928 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
929 ext2fs_inode_scan_goto_blockgroup which allows an
930 application to jump to a particular block group while
933 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
935 * dirblock.c: Include string.h, since we use memcpy().
937 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
939 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
940 a long not an int; this doesn't matter on i386 machines,
941 but it does on Alpha's.
943 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
945 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
946 table pointer is NULL, then return an error indicating
947 that the inode table is missing.
948 (get_next_blockgroup, get_next_blocks,
949 ext2fs_get_next_inode): Don't treat a missing inode table
950 as permanent error. Return MISSING_INODE_TABLE, but as an
951 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
953 * rw_bitmaps.c (ext2fs_write_block_bitmap,
954 ext2fs_write_inode_bitmap): If the inode or block bitmap
955 block is zero, then don't write out the inode or block
956 bitmap. The idea here is to avoid stomping on the
958 (read_bitmaps): If the inode or block bitmap block is
959 zero, then fill in that portion of the inode or block
960 bitmap with all zeros.
962 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
963 blocks in inode table when the inode table size is
964 non-standard (and can therefore span blocks).
966 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
968 * alloc.c (ext2fs_new_block): Fix fencepost error in
969 ext2fs_new_block; make sure we don't try to allocate the
970 first block beyond the end of the filesystem.
972 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
974 * inode.c (check_for_inode_bad_blocks): New function called by
975 get_next_blocks() to avoid reading in bad blocks marked in
976 fs->badblocks. Inodes located in bad blocks are returned
977 by ext2fs_get_next_inode() returns the error code
978 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
980 * alloc_tables.c (ext2fs_allocate_tables): New function which
981 performs the part of mke2fs's job of allocating the
984 * test_io.c (test_close): IO manager which is used for testing
987 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
989 * inode.c (ext2fs_get_next_inode): Separate out the function of
990 setting up for a new block group to get_next_blockgroup().
991 Separate out the function of reading in blocks of the
992 inode table to get_next_blocks().
994 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
996 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
997 blocks to the badblock list in sorted order. This allows
998 badblocks_list_test to be coded using a binary search for
1001 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1003 * Release of E2fsprogs version 1.06
1005 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1007 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
1008 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
1011 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
1012 set, then only write out the master superblock.
1014 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1016 * block.c (ext2fs_block_iterate): Fixed bug which caused
1017 block_iterate to fail to handle HURD created filesystems;
1018 it tested the inode translator field before the inode was
1021 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1023 * initialize.c (ext2fs_initialize): Make sure the description for
1024 the inode bitmap is set correctly.
1026 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
1028 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1030 * Release of E2fsprogs version 1.05
1032 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1034 * initialize.c: Override the kernel's idea of default
1035 checkinterval from 0 (never) to 180 days.

1044 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
1045 for shortcut function fs->read_inode() and fs->write_inode().
1046 Added inode_cache to reduce CPU time spent in doing

1052 * namei.c (ext2fs_follow_link): New function.
1053 (ext2fs_namei): Extended to have support for chasing
1054 symbolic links. ext2fs_namei() still returns an inode
1055 which is a symbolic link. Symbolic links are only chased
1056 while resolving the containing directory. To chase
1057 symbolic links of the final result, use
1058 ext2fs_follow_link().
1060 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1062 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
1064 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
1065 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).

1069 * initialize.c (ext2fs_initialize): On systems where the byte
1070 order is not i386 compatible, set the swap_byte flag.
1072 * inode.c (inocpy_with_swap): Check to see if inode contains a
1073 fast symlink before swapping the inode block fields. This
1074 required adding a new argument to inocpy_with_swap to
1075 determine whether the mode field is in host order or not.
1077 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1079 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
1080 the sparc, if EXT2_STD_BITOPS set, use the standard
1081 i386-compatible bitmask operations, instead on the
1082 non-standard native bitmask operators.

1086 * block.c (ext2fs_block_iterate): Cause block iterator to return
1087 the HURD translator block (along with everything else).

1089 iterator, then don't return any meta data blocks
1090 (including the HURD translator).
1092 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1094 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
1096 * uuid.c: New file, containing UUID utility functions.
1098 Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1100 * ext2fs.h: Add a definition of the "real" ext2 superblock.

1106 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
1108 * openfs.c (ext2fs_open): If the blocksize in the superblock is
1109 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
1110 that's a basic value that must be correct for the rest of
1111 the library to work.
1113 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
1116 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

1127 Change the m68k bit numbering for bitmasks to match with
1128 the bit numbering used by all other ext2 implementations.

1152 Wed Feb 21 15:56:17 1996 <tytso@rsts-11.mit.edu>
1154 * getsize.c (ext2fs_get_device_size): Open the device read-only
1155 when trying to determine its size.
1157 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
1159 * Release of E2fsprogs version 1.02

1163 * rw_bitops.c (ext2fs_write_block_bitmap):
1164 * bitops.c (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1165 * bitops.h (ext2fs_test_bit, ext2fs_clear_bit, ext2fs_set_bit):
1166 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
1167 to avoid conflicts with with kernel include files. Also
1168 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
1171 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
1173 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
1175 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
1176 s_def_resuid and s_def_resgid for backwards compatibility.
1178 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>
1180 * bitops.h: Added #ifdef's for Sparc.
1182 Wed Sep 6 22:14:46 1995 <tytso@rsts-11.mit.edu>
1184 * getsize.c: #include <sys/ioctl.h> under Linux to pick up ioctl()
1187 * closefs.c: #include <string.h> to pick up memset() declaration
1189 Mon Sep 4 21:45:29 1995 Remy Card <card@bbj>
1191 * Makefile.in: Added support for BSD shared libraries.
1193 * initialize.c (ext2fs_initialize): Correctly set the s_creator_os
1196 Mon Sep 4 09:55:30 1995 <tytso@rsts-11.mit.edu>
1198 * unix_io.c (unix_open): Add a double check; if the passed in name
1199 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
1201 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
1203 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

1225 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
1226 Move these functions to freefs.c.
1228 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
1229 descriptors shadow memory to keep purify quiet. (This
1230 also has the nice benefit that the unused portion of the
1231 shadow descriptors are zeroed out.)
1233 * dirblock.c (ext2fs_write_dir_block): We need to use
1234 dirent->rec_len *before* it's byteswapped to find the
1235 location of the next directory structure!
1237 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
1238 cause ext2fs_new_inode to loop infinitely if we're trying
1239 to allocate an inode in group #0 and there are no free
1240 inodes at all in the system.
1242 * closefs.c: #include <errno.h> if it exists.
1244 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1246 * ext2fs.h (BLOCK_FLAG_HOLE): Added new definition for

1252 * Makefile.in (DLL_INSTALL_DIR, ELF_INSTALL_DIR): Set the
1253 installation directories correctly.
1255 Tue Jul 18 09:27:38 1995 <tytso@rsx-11.mit.edu>

1263 file containing functions for reading and writing
1264 directory blocks (byte swapping if necesssary)
1266 * block.c (block_iterate_ind, block_iterate_dind,
1267 block_iterate_tind): Byte swap the block addresses if
1268 EXT2_SWAP_BYTES is set (and swap them back before writing
1271 * inode.c (inocpy_with_swap): New function.
1272 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
1273 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
1275 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
1276 the superblock and group descriptors before writing it out.
1278 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
1279 then set the EXT2_SWAP_BYTES and byte-swap the superblock
1280 and group descriptors.
1282 * swapfs.c (ext2fs_swap_super, ext2fs_swap_group_desc): New functions
1283 to desp ext2 filesystem structures.
1285 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
1286 supplied by Pete A. Zaitcev so that the C language
1287 versions of these functions are more portable. They will
1288 now work on both little and big endian systems, and the
1289 assumption that 32-bit integers are used is gone.
1291 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
1292 doing byte swapping.
1294 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
1295 byte swapping should take place.
1297 Sun Jul 16 06:21:43 1995 <tytso@rsx-11.mit.edu>

1306 Sat Jul 15 04:23:37 1995 <tytso@rsx-11.mit.edu>
1308 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
1309 if the magic number is correct, it will be allocated.
1311 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
1313 * block.c (block_iterate_ind, block_iterate_dind,
1314 block_iterate_tind): Don't recompute block_nr each loop;
1315 just increment it! Factor check of BLOCK_FLAG_APPEND out
1316 of the loop. Factor mask of BLOCK_CHANGED into changed
1317 variable out of the loop. (block_iterate_ind, in
1318 particular, gets called a lot, so every little
1319 optimization helps.)
1321 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
1323 * block.c (block_iterate_ind, block_iterate_dind,

1325 block_iterate_ind and company.
1327 * bitops.h (ext2fs_fast_mark_block_bitmap,
1328 ext2fs_fast_unmark_block_bitmap, ext2fs_fast_test_block_bitmap,
1329 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
1330 ext2fs_fast_test_inode_bitmap): Add fast version of these
1331 functions, which don't do range checking.
1333 * bitops.h (ext2fs_get_block_bitmap_start,
1334 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
1335 ext2fs_get_inode_bitmap_end): Add new accessor functions
1336 which return the start and end points of the bitmaps.
1338 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
1340 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
1341 instead of llseek. The errno if the offset is too large
1342 and lseek is not supported should be EINVAL, not -EINVAL.
1344 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1346 * Makefile.in: Added support for ELF shared libraries.
1347 Fixed typos in the compilation rules.
1348 (distclean): Added Makefile.

1354 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1356 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1358 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1360 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1362 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1363 the S_*, which are normally defined in <sys/stat.h>. This
1364 allows us to compile e2fsprogs on a non-Linux system,
1365 which may have a different value for S_IFDIR.
1367 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1369 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
1370 this is a user-mode application!
1372 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1374 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef
1375 __linux__ so that non-linux systems won't see it.
1377 * alloc.c: Include <errno.h> if possible.
1378 * badblocks.c: Ditto.
1379 * bb_inode.c: Ditto.
1382 * expanddir.c: Ditto.
1383 * get_pathname.c: Ditto.
1384 * initialize.c: Ditto.
1391 * rw_bitmaps.c: Ditto.
1394 * Makefile.in: Rewritten to conform to GNU coding standards and
1395 support separate compilation directories.
1397 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1399 * initialize.c (ext2fs_initialize): Don't allow more than one
1400 bitmaps's worth of inodes in a group.
1402 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1404 * llseek.c (ext2_llseek): Added error checking to the llseek()
1405 compat code to protect against overflow. This only
1406 applies to 1.0 and early 1.1 kernels, which don't support
1407 the llseek() system call.
1409 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1411 * unix_io.c (unix_open): Initialize the read_error and write_error
1412 io_channel pointers to be null.
1414 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1415 found, clear it but don't try to update the filesystem
1416 accounting information, since that's hopeless anyway.
1418 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1419 bloblock_iterate_tind): Check to see if the indirect blocks are
1420 valid before trying to read them.

1423 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1425 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1426 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1427 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1428 illegal block or inode number is passed in, return instead
1429 of trying to test, set, or clear the bit.
1431 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1433 * Makefile: Added a dummy install target in case shared libraries

1447 the inode and block bitmaps.
1449 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1450 magic number for a block bitmap instead of an inode bitmap.

1456 badblocks_list_test, badblocks_list_iterate_begin,
1457 badblocks_list_iterate, badblocks_list_iterate_end): Add
1458 magic number checking for the badblocks_list and
1459 badblocks_iterate structures.
1461 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1462 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,
1463 unix_write_blk, unix_flush): Add magic number checking
1464 both for io_channel structure and unix_private_data
1467 * openfs.c (ext2fs_open): Add check for io_manager structure's
1470 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1471 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1472 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1473 * read_bb.c (ext2fs_read_bb_inode):
1474 * read_bb_file.c (ext2fs_read_bb_FILE):

1483 * block.c (ext2fs_block_iterate):
1484 * bitmaps.c (ext2fs_allocate_inode_bitmap,
1485 ext2fs_allocate_block_bitmap):
1486 * bb_inode.c (ext2fs_update_bb_inode):
1487 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):
1488 * check_desc.c (ext2fs_check_desc):
1489 * closefs.c (ext2fs_close, ext2fs_flush):
1490 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.
1495 * check_desc.c (ext2fs_check_desc): Move ext2fs_check_desc from
1496 openfs.c into its own file.
1498 * ext2fs.h (EXT2_CHECK_MAGIC): Added macro for checking for
1499 structure magic numbers.
1501 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1502 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1503 someone uses the -b option to specify the use of the backup
1504 superblock --- this usually means that the main superblock is
1508 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1509 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1510 revision level to the superblock.
1512 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1519 * initialize.c: Completely revamped the inode and block bitmap
1520 structures, so that they can be better chance of being extensible
1521 in a shared library. They are now their own type, instead of
1522 being a char *. Also, the function signatures of
1523 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1524 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1525 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1526 changed to eliminate the ext2_filsys argument, since it is no
1529 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1531 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1532 system call if available.
1534 * llseek.c: new file. This is the stub calling the llseek system
1535 call which allows supports for 2GB+ file systems.

1538 the creator operating system.
1540 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1542 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1543 the group descriptor statistics in addition to everything else.
1544 This relieves mke2fs of the responsibility of doing it.
1546 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1547 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1548 not the generic C function equivalents should be included or not.
1550 * openfs.c (ext2fs_open): If a superblock is specified, then use
1551 the backup group descriptors that go along with this superblock,
1552 instead of using the primary group descriptors. This allows
1553 e2fsck to recover filesystems where the primary group descriptors
