13 fsync to flush the kernel buffers to disk.
15 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
17 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
18 current inode number wasn't being set by the
19 goto_blockgroup function.
21 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
23 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
24 of blocks which need to be moved, and moves those blocks
25 to another location in the filesystem.
27 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
28 bitmap, make sure all of the new parts of the bitmap are

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

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

103 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
105 (unix_close, test_close): Decrement the refcount and only
106 close the io_channel if the refcount goes to 0.
108 * io.h: Add refcount to the io_channel structure. Add new macro
109 interface io_channel_bumpcount() to bump the refcount.
111 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
113 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
114 cache in the filesystem handle, instead of the inode cache
115 in a static variable.
117 * freefs.c: Added static function to free the inode cache (called by
120 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
122 * ext2fs.h: Added pointer to the inode_cache structure.
124 * block.c (block_iterate_ind, block_iterate_dind,
125 block_iterate_tind): If there are holes in the indirect,
126 doubly indirect, or triply indirect blocks, increment the
127 block count field automatically.
129 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
131 * Release of E2fsprogs version 1.09
133 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
135 * version.c (ext2fs_parse_version_string): Check the passed in
136 version string (instead of the hard-coded one).
138 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
139 greater filesystem size, clamp it to prevent allocating a
140 block or inode bitmap beyond the filesystem.
142 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
143 overhead calculation was accidentally removed.
145 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
147 * Release of E2fsprogs version 1.08
149 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

152 block of a dblist entry, given the directory inode and
155 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
157 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
158 inode bitmaps at staggered locations across the block
159 groups, to avoid concentrating the bitmaps on a small
160 number of disks when using striped RAID arrays.
162 * initialize.c (ext2fs_initialize): By default, choose the maximum
163 possible number of blocks per group (based on the size of
164 the bitmaps in the blocksize).
166 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
168 * initialize.c (ext2fs_initialize): Add support for
169 EXT2_COMPAT_SPARSE_SUPER feature.
171 * closefs.c (ext2fs_bg_has_super): New function to determine
172 whether or a particular block group should have a
173 superblock and block group descriptor. Used for the
174 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
175 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
176 or not the superblock should be written out for the block
179 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
180 for sparse duplicate superblocks.
182 * version.c (ext2fs_get_library_version): New function which
183 returns the library version.
185 * version.c (ext2fs_parse_version_string): New function which
186 parses a version string and returns a version number,
187 so application programs can compare version numbers as
190 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
192 * icount.c (ext2fs_create_icount): Change function so that it also
193 takes a new argument which contains a "hint" icount
194 structure. This "hint" icount allows the create function
195 to set up the sorted list in advance. This reduces
196 significantly the amount of data moving needed to insert
197 these inodes into the list later.
199 * icount.c (ext2fs_icount_validate): New function which validates
200 that the icount structure's rep invariant.
202 * icount.c (get_icount_el): Completely revamped implementation
203 to subsume put_icount_el(). Put_icount_el() used to
204 use an O(N) implementation to insert in the middle
205 of the icount list. It now uses a O(ln N) to search
206 for where the icount should be inserted, and then uses
207 a memcpy to move the list down (instead of a for loop).
209 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
210 ext2fs_icount_increment, ext2fs_icount_decrement): Check
211 to see if the inode is within bounds; if it isn't, return
214 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
215 when a bad inode number is passed to test_generic_bitmap
216 to be EXT2FS_TEST_ERROR instead of the wrong
219 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
221 * Release of E2fsprogs version 1.07
223 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
225 * Makefile.in (ELF_VERSION): Change version to be 2.2
227 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
229 * alloc.c (ext2fs_get_free_blocks): Change routine to use
230 ext2fs_fast_test_block_bitmap_range().
232 * bitops.h (ext2fs_fast_test_block_bitmap_range,
233 ext2fs_test_block_bitmap_range: New inline functions which
234 test to see whether a contiguous range of blocks is
237 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
239 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
240 use ext2fs_badblocks_* instead of badblocks_*
242 * bb_compat.c: New file which translates between old badblocks_*()
243 names to ext2fs_badblocks_*()
245 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
246 link.c (since e2fsck doesn't use ext2fs_unlink()).
248 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
249 bitmap resizing routine moved from bitmaps.c, since e2fsck
250 doesn't need to use this function.
252 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
253 since e2fsck only needs ext2fs_lookup.
255 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
257 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
258 already set; this is needed so that programs like dump
259 which use the inode scan functions will deal with
260 filesystems that have bad blocks in the inode table.
262 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
264 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
265 Moved to ext2fsP.h, since it doesn't need to be part of
266 the public interface.
268 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
270 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
272 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
273 directory block list abstraction. (Code moved from
276 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
277 to inode.c (since no one else should be peeking inside it!)
279 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
281 * openfs.c (ext2fs_open): Check the feature set in the ext2
282 superblock, and refuse to open filesystems if they contain
283 incompatible features. (Can be overriden with the
286 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
288 * block.c (ext2fs_block_iterate2): Added new function
289 ext2fs_block_iterate2 which changes the function
290 signature of the callback function to include the
291 referencing block and offset.
293 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
294 ext2fs_inode_scan_goto_blockgroup which allows an
295 application to jump to a particular block group while
298 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
300 * dirblock.c: Include string.h, since we use memcpy().
302 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
304 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
305 a long not an int; this doesn't matter on i386 machines,
306 but it does on Alpha's.
308 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
310 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
311 table pointer is NULL, then return an error indicating
312 that the inode table is missing.
313 (get_next_blockgroup, get_next_blocks,
314 ext2fs_get_next_inode): Don't treat a missing inode table
315 as permanent error. Return MISSING_INODE_TABLE, but as an
316 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
318 * rw_bitmaps.c (ext2fs_write_block_bitmap,
319 ext2fs_write_inode_bitmap): If the inode or block bitmap
320 block is zero, then don't write out the inode or block
321 bitmap. The idea here is to avoid stomping on the
323 (read_bitmaps): If the inode or block bitmap block is
324 zero, then fill in that portion of the inode or block
325 bitmap with all zeros.
327 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
328 blocks in inode table when the inode table size is
329 non-standard (and can therefore span blocks).
331 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
333 * alloc.c (ext2fs_new_block): Fix fencepost error in
334 ext2fs_new_block; make sure we don't try to allocate the
335 first block beyond the end of the filesystem.
337 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
339 * inode.c (check_for_inode_bad_blocks): New function called by
340 get_next_blocks() to avoid reading in bad blocks marked in
341 fs->badblocks. Inodes located in bad blocks are returned
342 by ext2fs_get_next_inode() returns the error code
343 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
345 * alloc_tables.c (ext2fs_allocate_tables): New function which
346 performs the part of mke2fs's job of allocating the
349 * test_io.c (test_close): IO manager which is used for testing
352 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
354 * inode.c (ext2fs_get_next_inode): Separate out the function of
355 setting up for a new block group to get_next_blockgroup().
356 Separate out the function of reading in blocks of the
357 inode table to get_next_blocks().
359 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
361 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
362 blocks to the badblock list in sorted order. This allows
363 badblocks_list_test to be coded using a binary search for
366 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
368 * Release of E2fsprogs version 1.06
370 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
372 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
373 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
376 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
377 set, then only write out the master superblock.
379 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
381 * block.c (ext2fs_block_iterate): Fixed bug which caused
382 block_iterate to fail to handle HURD created filesystems;
383 it tested the inode translator field before the inode was
386 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
388 * initialize.c (ext2fs_initialize): Make sure the description for
389 the inode bitmap is set correctly.
391 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

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

434 * initialize.c (ext2fs_initialize): On systems where the byte
435 order is not i386 compatible, set the swap_byte flag.
437 * inode.c (inocpy_with_swap): Check to see if inode contains a
438 fast symlink before swapping the inode block fields. This
439 required adding a new argument to inocpy_with_swap to
440 determine whether the mode field is in host order or not.
442 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
444 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
445 the sparc, if EXT2_STD_BITOPS set, use the standard
446 i386-compatible bitmask operations, instead on the
447 non-standard native bitmask operators.
449 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
451 * block.c (ext2fs_block_iterate): Cause block iterator to return
452 the HURD translator block (along with everything else).
453 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
454 iterator, then don't return any meta data blocks
455 (including the HURD translator).
457 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
459 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.

469 * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
471 Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
473 * openfs.c (ext2fs_open): If the blocksize in the superblock is
474 zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
475 that's a basic value that must be correct for the rest of
478 * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
481 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
483 * Release of E2fsprogs version 1.04

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

531 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
532 to avoid conflicts with with kernel include files. Also
533 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

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

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

628 file containing functions for reading and writing
629 directory blocks (byte swapping if necesssary)
631 * block.c (block_iterate_ind, block_iterate_dind,

636 * inode.c (inocpy_with_swap): New function.
637 (ext2fs_get_next_inode, ext2fs_read_inode, ext2fs_write_inode):
638 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
640 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
641 the superblock and group descriptors before writing it out.
643 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
644 then set the EXT2_SWAP_BYTES and byte-swap the superblock
645 and group descriptors.

648 to desp ext2 filesystem structures.
650 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
651 supplied by Pete A. Zaitcev so that the C language
652 versions of these functions are more portable. They will
653 now work on both little and big endian systems, and the
654 assumption that 32-bit integers are used is gone.
656 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
659 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that

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

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

742 * alloc.c: Include <errno.h> if possible.
743 * badblocks.c: Ditto.
747 * expanddir.c: Ditto.
748 * get_pathname.c: Ditto.
749 * initialize.c: Ditto.
756 * rw_bitmaps.c: Ditto.
759 * Makefile.in: Rewritten to conform to GNU coding standards and
760 support separate compilation directories.

764 * initialize.c (ext2fs_initialize): Don't allow more than one
765 bitmaps's worth of inodes in a group.

770 compat code to protect against overflow. This only
771 applies to 1.0 and early 1.1 kernels, which don't support
772 the llseek() system call.
774 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
776 * unix_io.c (unix_open): Initialize the read_error and write_error
777 io_channel pointers to be null.
779 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
780 found, clear it but don't try to update the filesystem
781 accounting information, since that's hopeless anyway.
783 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
784 bloblock_iterate_tind): Check to see if the indirect blocks are
785 valid before trying to read them.
787 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
788 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
790 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,

792 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
793 illegal block or inode number is passed in, return instead
794 of trying to test, set, or clear the bit.
796 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
798 * Makefile: Added a dummy install target in case shared libraries

823 magic number checking for the badblocks_list and
824 badblocks_iterate structures.
826 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
827 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,

867 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
868 someone uses the -b option to specify the use of the backup
869 superblock --- this usually means that the main superblock is
873 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
874 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
875 revision level to the superblock.
877 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
884 * initialize.c: Completely revamped the inode and block bitmap
885 structures, so that they can be better chance of being extensible
886 in a shared library. They are now their own type, instead of
887 being a char *. Also, the function signatures of
888 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
889 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
890 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
891 changed to eliminate the ext2_filsys argument, since it is no
894 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
896 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
897 system call if available.
899 * llseek.c: new file. This is the stub calling the llseek system

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