4 fsync to flush the kernel buffers to disk.
6 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
8 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
9 current inode number wasn't being set by the
10 goto_blockgroup function.
12 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
14 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
15 of blocks which need to be moved, and moves those blocks
16 to another location in the filesystem.
18 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a

25 wasn't being returned to the caller.
27 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
28 ext2fs_allocate_group_table() which sets the group tables
29 for a particular block group. The relevant code was
30 factored out of ext2fs_allocate_tables().
32 * dblist.c (make_dblist): Adjust the initial size of the directory
33 block list to be a bit more realize (ten plus twice the
34 number of directories in the filesystem).
36 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
38 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
39 ext2fs_badblocks_list_test would test the list (and exceed
40 array boundaries) if there were no bad blocks on the bad
41 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
43 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
45 * Release of E2fsprogs version 1.10
47 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
49 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
50 inode and block bitmaps based on the RAID 0 stride
51 parameter (which is passed by mke2fs).
53 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
54 mke2fs to communicate the stride length to
55 ext2fs_allocate_tables()
57 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
59 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2

94 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
96 (unix_close, test_close): Decrement the refcount and only
97 close the io_channel if the refcount goes to 0.
99 * io.h: Add refcount to the io_channel structure. Add new macro
100 interface io_channel_bumpcount() to bump the refcount.
102 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
104 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
105 cache in the filesystem handle, instead of the inode cache
106 in a static variable.
108 * freefs.c: Added static function to free the inode cache (called by
111 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
113 * ext2fs.h: Added pointer to the inode_cache structure.
115 * block.c (block_iterate_ind, block_iterate_dind,
116 block_iterate_tind): If there are holes in the indirect,
117 doubly indirect, or triply indirect blocks, increment the
118 block count field automatically.
120 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
122 * Release of E2fsprogs version 1.09
124 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
126 * version.c (ext2fs_parse_version_string): Check the passed in
127 version string (instead of the hard-coded one).
129 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
130 greater filesystem size, clamp it to prevent allocating a
131 block or inode bitmap beyond the filesystem.
133 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
134 overhead calculation was accidentally removed.
136 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
138 * Release of E2fsprogs version 1.08
140 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
142 * dblist.c (ext2fs_set_dir_block): New function which sets the
143 block of a dblist entry, given the directory inode and
146 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
148 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
149 inode bitmaps at staggered locations across the block
150 groups, to avoid concentrating the bitmaps on a small
151 number of disks when using striped RAID arrays.
153 * initialize.c (ext2fs_initialize): By default, choose the maximum
154 possible number of blocks per group (based on the size of
155 the bitmaps in the blocksize).
157 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
159 * initialize.c (ext2fs_initialize): Add support for
160 EXT2_COMPAT_SPARSE_SUPER feature.
162 * closefs.c (ext2fs_bg_has_super): New function to determine
163 whether or a particular block group should have a
164 superblock and block group descriptor. Used for the
165 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
166 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
167 or not the superblock should be written out for the block
170 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
171 for sparse duplicate superblocks.
173 * version.c (ext2fs_get_library_version): New function which
174 returns the library version.

178 so application programs can compare version numbers as
181 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
183 * icount.c (ext2fs_create_icount): Change function so that it also
184 takes a new argument which contains a "hint" icount
185 structure. This "hint" icount allows the create function
186 to set up the sorted list in advance. This reduces
187 significantly the amount of data moving needed to insert
188 these inodes into the list later.
190 * icount.c (ext2fs_icount_validate): New function which validates
191 that the icount structure's rep invariant.
193 * icount.c (get_icount_el): Completely revamped implementation
194 to subsume put_icount_el(). Put_icount_el() used to
195 use an O(N) implementation to insert in the middle
196 of the icount list. It now uses a O(ln N) to search
197 for where the icount should be inserted, and then uses
198 a memcpy to move the list down (instead of a for loop).
200 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
201 ext2fs_icount_increment, ext2fs_icount_decrement): Check
202 to see if the inode is within bounds; if it isn't, return
205 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
206 when a bad inode number is passed to test_generic_bitmap
207 to be EXT2FS_TEST_ERROR instead of the wrong
210 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
212 * Release of E2fsprogs version 1.07
214 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
216 * Makefile.in (ELF_VERSION): Change version to be 2.2
218 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
220 * alloc.c (ext2fs_get_free_blocks): Change routine to use
221 ext2fs_fast_test_block_bitmap_range().
223 * bitops.h (ext2fs_fast_test_block_bitmap_range,
224 ext2fs_test_block_bitmap_range: New inline functions which
225 test to see whether a contiguous range of blocks is
228 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
230 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
231 use ext2fs_badblocks_* instead of badblocks_*
233 * bb_compat.c: New file which translates between old badblocks_*()
234 names to ext2fs_badblocks_*()
236 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
237 link.c (since e2fsck doesn't use ext2fs_unlink()).
239 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
240 bitmap resizing routine moved from bitmaps.c, since e2fsck
241 doesn't need to use this function.
243 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
244 since e2fsck only needs ext2fs_lookup.
246 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
248 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
249 already set; this is needed so that programs like dump
250 which use the inode scan functions will deal with
251 filesystems that have bad blocks in the inode table.
253 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
255 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
256 Moved to ext2fsP.h, since it doesn't need to be part of
257 the public interface.
259 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
261 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
263 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
264 directory block list abstraction. (Code moved from
267 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
268 to inode.c (since no one else should be peeking inside it!)
270 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
272 * openfs.c (ext2fs_open): Check the feature set in the ext2
273 superblock, and refuse to open filesystems if they contain
274 incompatible features. (Can be overriden with the
277 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
279 * block.c (ext2fs_block_iterate2): Added new function
280 ext2fs_block_iterate2 which changes the function
281 signature of the callback function to include the
282 referencing block and offset.
284 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
285 ext2fs_inode_scan_goto_blockgroup which allows an
286 application to jump to a particular block group while
289 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
291 * dirblock.c: Include string.h, since we use memcpy().
293 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
295 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
296 a long not an int; this doesn't matter on i386 machines,
297 but it does on Alpha's.
299 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
301 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
302 table pointer is NULL, then return an error indicating
303 that the inode table is missing.
304 (get_next_blockgroup, get_next_blocks,
305 ext2fs_get_next_inode): Don't treat a missing inode table
306 as permanent error. Return MISSING_INODE_TABLE, but as an
307 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
309 * rw_bitmaps.c (ext2fs_write_block_bitmap,
310 ext2fs_write_inode_bitmap): If the inode or block bitmap
311 block is zero, then don't write out the inode or block
312 bitmap. The idea here is to avoid stomping on the
314 (read_bitmaps): If the inode or block bitmap block is
315 zero, then fill in that portion of the inode or block
316 bitmap with all zeros.
318 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
319 blocks in inode table when the inode table size is
320 non-standard (and can therefore span blocks).
322 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
324 * alloc.c (ext2fs_new_block): Fix fencepost error in
325 ext2fs_new_block; make sure we don't try to allocate the
326 first block beyond the end of the filesystem.
328 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
330 * inode.c (check_for_inode_bad_blocks): New function called by
331 get_next_blocks() to avoid reading in bad blocks marked in
332 fs->badblocks. Inodes located in bad blocks are returned
333 by ext2fs_get_next_inode() returns the error code
334 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
336 * alloc_tables.c (ext2fs_allocate_tables): New function which
337 performs the part of mke2fs's job of allocating the
340 * test_io.c (test_close): IO manager which is used for testing

345 * inode.c (ext2fs_get_next_inode): Separate out the function of
346 setting up for a new block group to get_next_blockgroup().
347 Separate out the function of reading in blocks of the
348 inode table to get_next_blocks().
350 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
352 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
353 blocks to the badblock list in sorted order. This allows
354 badblocks_list_test to be coded using a binary search for
357 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
359 * Release of E2fsprogs version 1.06

363 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
364 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
367 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
368 set, then only write out the master superblock.
370 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
372 * block.c (ext2fs_block_iterate): Fixed bug which caused
373 block_iterate to fail to handle HURD created filesystems;
374 it tested the inode translator field before the inode was
377 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
379 * initialize.c (ext2fs_initialize): Make sure the description for
380 the inode bitmap is set correctly.

408 * namei.c (ext2fs_follow_link): New function.
409 (ext2fs_namei): Extended to have support for chasing
410 symbolic links. ext2fs_namei() still returns an inode
411 which is a symbolic link. Symbolic links are only chased
412 while resolving the containing directory. To chase
413 symbolic links of the final result, use
414 ext2fs_follow_link().
416 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

425 * initialize.c (ext2fs_initialize): On systems where the byte
426 order is not i386 compatible, set the swap_byte flag.
428 * inode.c (inocpy_with_swap): Check to see if inode contains a
429 fast symlink before swapping the inode block fields. This
430 required adding a new argument to inocpy_with_swap to
431 determine whether the mode field is in host order or not.
433 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
435 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
436 the sparc, if EXT2_STD_BITOPS set, use the standard
437 i386-compatible bitmask operations, instead on the
438 non-standard native bitmask operators.
440 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
442 * block.c (ext2fs_block_iterate): Cause block iterator to return
443 the HURD translator block (along with everything else).

462 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
464 * openfs.c (ext2fs_open): If the blocksize in the superblock is
465 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
466 that's a basic value that must be correct for the rest of
469 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
472 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

483 Change the m68k bit numbering for bitmasks to match with
484 the bit numbering used by all other ext2 implementations.
486 Thu Mar 7 03:37:00 1996 <tytso@rsts-11.mit.edu>
488 * inode.c (ext2fs_get_next_inode, ext2fs_close_inode_scan,

555 is NULL, return EXT2_ET_BAD_DEVICE_NAME.
557 * ext2_err.et (EXT2_ET_BAD_DEVICE_NAME): Added new error code
559 Wed Aug 16 15:44:10 1995 <tytso@rsts-11.mit.edu>

581 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
582 Move these functions to freefs.c.
584 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
585 descriptors shadow memory to keep purify quiet. (This
586 also has the nice benefit that the unused portion of the
587 shadow descriptors are zeroed out.)
589 * dirblock.c (ext2fs_write_dir_block): We need to use
590 dirent->rec_len *before* it's byteswapped to find the
591 location of the next directory structure!
593 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
594 cause ext2fs_new_inode to loop infinitely if we're trying
595 to allocate an inode in group #0 and there are no free
596 inodes at all in the system.
598 * closefs.c: #include <errno.h> if it exists.

619 file containing functions for reading and writing
620 directory blocks (byte swapping if necesssary)
622 * block.c (block_iterate_ind, block_iterate_dind,
623 block_iterate_tind): Byte swap the block addresses if
624 EXT2_SWAP_BYTES is set (and swap them back before writing
627 * inode.c (inocpy_with_swap): New function.
628 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
629 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
631 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
632 the superblock and group descriptors before writing it out.
634 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
635 then set the EXT2_SWAP_BYTES and byte-swap the superblock
636 and group descriptors.

639 to desp ext2 filesystem structures.
641 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
642 supplied by Pete A. Zaitcev so that the C language
643 versions of these functions are more portable. They will
644 now work on both little and big endian systems, and the
645 assumption that 32-bit integers are used is gone.
647 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
650 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
651 byte swapping should take place.

669 * block.c (block_iterate_ind, block_iterate_dind,
670 block_iterate_tind): Don't recompute block_nr each loop;
671 just increment it! Factor check of BLOCK_FLAG_APPEND out
672 of the loop. Factor mask of BLOCK_CHANGED into changed
673 variable out of the loop. (block_iterate_ind, in
674 particular, gets called a lot, so every little
677 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
679 * block.c (block_iterate_ind, block_iterate_dind,

689 * bitops.h (ext2fs_get_block_bitmap_start,
690 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
691 ext2fs_get_inode_bitmap_end): Add new accessor functions

694 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
696 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
697 instead of llseek. The errno if the offset is too large
698 and lseek is not supported should be EINVAL, not -EINVAL.
700 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
702 * Makefile.in: Added support for ELF shared libraries.
703 Fixed typos in the compilation rules.
704 (distclean): Added Makefile.
706 * llseek.c (llseek): New function, if llseek() does not exist in the
708 (ext2_llseek): Changed to call llseek().
710 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
712 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
714 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
716 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
718 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
719 the S_*, which are normally defined in <sys/stat.h>. This
720 allows us to compile e2fsprogs on a non-Linux system,
721 which may have a different value for S_IFDIR.
723 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
725 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
726 this is a user-mode application!
728 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
730 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef

733 * alloc.c: Include <errno.h> if possible.
734 * badblocks.c: Ditto.
738 * expanddir.c: Ditto.
739 * get_pathname.c: Ditto.
740 * initialize.c: Ditto.
747 * rw_bitmaps.c: Ditto.
750 * Makefile.in: Rewritten to conform to GNU coding standards and
751 support separate compilation directories.
753 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
755 * initialize.c (ext2fs_initialize): Don't allow more than one
756 bitmaps's worth of inodes in a group.

760 * llseek.c (ext2_llseek): Added error checking to the llseek()
761 compat code to protect against overflow. This only
762 applies to 1.0 and early 1.1 kernels, which don't support
763 the llseek() system call.
765 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
767 * unix_io.c (unix_open): Initialize the read_error and write_error
768 io_channel pointers to be null.
770 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
771 found, clear it but don't try to update the filesystem
772 accounting information, since that's hopeless anyway.
774 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
775 bloblock_iterate_tind): Check to see if the indirect blocks are
776 valid before trying to read them.
778 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
779 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
781 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
782 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
783 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
784 illegal block or inode number is passed in, return instead
785 of trying to test, set, or clear the bit.
787 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
789 * Makefile: Added a dummy install target in case shared libraries
792 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)

813 badblocks_list_iterate, badblocks_list_iterate_end): Add
814 magic number checking for the badblocks_list and
815 badblocks_iterate structures.
817 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
818 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,

845 * closefs.c (ext2fs_close, ext2fs_flush):
846 * freefs.c (ext2fs_free): Add check for ext2_filsys magic number.

857 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
858 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
859 someone uses the -b option to specify the use of the backup
860 superblock --- this usually means that the main superblock is
864 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
865 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
866 revision level to the superblock.
868 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
875 * initialize.c: Completely revamped the inode and block bitmap
876 structures, so that they can be better chance of being extensible
877 in a shared library. They are now their own type, instead of
878 being a char *. Also, the function signatures of
879 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
880 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
881 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
882 changed to eliminate the ext2_filsys argument, since it is no
885 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
887 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
888 system call if available.
890 * llseek.c: new file. This is the stub calling the llseek system
891 call which allows supports for 2GB+ file systems.

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