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

38 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
39 wasn't being returned to the caller.
41 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
42 ext2fs_allocate_group_table() which sets the group tables
43 for a particular block group. The relevant code was
44 factored out of ext2fs_allocate_tables().
46 * dblist.c (make_dblist): Adjust the initial size of the directory
47 block list to be a bit more realistic (ten plus twice the
48 number of directories in the filesystem).
50 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
52 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
53 ext2fs_badblocks_list_test would test the list (and exceed
54 array boundaries) if there were no bad blocks on the bad
55 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
57 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
59 * Release of E2fsprogs version 1.10
61 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
63 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
64 inode and block bitmaps based on the RAID 0 stride
65 parameter (which is passed by mke2fs).
67 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
68 mke2fs to communicate the stride length to
69 ext2fs_allocate_tables()
71 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
73 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
74 systems. (We can't assume that the new filesystem types

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

192 so application programs can compare version numbers as
195 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
197 * icount.c (ext2fs_create_icount): Change function so that it also
198 takes a new argument which contains a "hint" icount
199 structure. This "hint" icount allows the create function
200 to set up the sorted list in advance. This reduces
201 significantly the amount of data moving needed to insert
202 these inodes into the list later.
204 * icount.c (ext2fs_icount_validate): New function which validates
205 that the icount structure's rep invariant.
207 * icount.c (get_icount_el): Completely revamped implementation
208 to subsume put_icount_el(). Put_icount_el() used to
209 use an O(N) implementation to insert in the middle
210 of the icount list. It now uses a O(ln N) to search
211 for where the icount should be inserted, and then uses
212 a memcpy to move the list down (instead of a for loop).
214 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
215 ext2fs_icount_increment, ext2fs_icount_decrement): Check
216 to see if the inode is within bounds; if it isn't, return
219 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
220 when a bad inode number is passed to test_generic_bitmap
221 to be EXT2FS_TEST_ERROR instead of the wrong
224 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
226 * Release of E2fsprogs version 1.07
228 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
230 * Makefile.in (ELF_VERSION): Change version to be 2.2
232 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
234 * alloc.c (ext2fs_get_free_blocks): Change routine to use
235 ext2fs_fast_test_block_bitmap_range().
237 * bitops.h (ext2fs_fast_test_block_bitmap_range,
238 ext2fs_test_block_bitmap_range: New inline functions which
239 test to see whether a contiguous range of blocks is
242 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
244 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
245 use ext2fs_badblocks_* instead of badblocks_*
247 * bb_compat.c: New file which translates between old badblocks_*()
248 names to ext2fs_badblocks_*()
250 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
251 link.c (since e2fsck doesn't use ext2fs_unlink()).
253 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
254 bitmap resizing routine moved from bitmaps.c, since e2fsck
255 doesn't need to use this function.
257 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
258 since e2fsck only needs ext2fs_lookup.
260 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
262 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
263 already set; this is needed so that programs like dump
264 which use the inode scan functions will deal with
265 filesystems that have bad blocks in the inode table.
267 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
269 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
270 Moved to ext2fsP.h, since it doesn't need to be part of
271 the public interface.
273 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
275 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
277 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
278 directory block list abstraction. (Code moved from
281 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
282 to inode.c (since no one else should be peeking inside it!)
284 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
286 * openfs.c (ext2fs_open): Check the feature set in the ext2
287 superblock, and refuse to open filesystems if they contain
288 incompatible features. (Can be overriden with the
291 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
293 * block.c (ext2fs_block_iterate2): Added new function
294 ext2fs_block_iterate2 which changes the function
295 signature of the callback function to include the
296 referencing block and offset.
298 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
299 ext2fs_inode_scan_goto_blockgroup which allows an
300 application to jump to a particular block group while
303 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
305 * dirblock.c: Include string.h, since we use memcpy().
307 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
309 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
310 a long not an int; this doesn't matter on i386 machines,
311 but it does on Alpha's.
313 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
315 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
316 table pointer is NULL, then return an error indicating
317 that the inode table is missing.
318 (get_next_blockgroup, get_next_blocks,
319 ext2fs_get_next_inode): Don't treat a missing inode table
320 as permanent error. Return MISSING_INODE_TABLE, but as an
321 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
323 * rw_bitmaps.c (ext2fs_write_block_bitmap,
324 ext2fs_write_inode_bitmap): If the inode or block bitmap
325 block is zero, then don't write out the inode or block
326 bitmap. The idea here is to avoid stomping on the
328 (read_bitmaps): If the inode or block bitmap block is
329 zero, then fill in that portion of the inode or block
330 bitmap with all zeros.
332 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
333 blocks in inode table when the inode table size is
334 non-standard (and can therefore span blocks).
336 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
338 * alloc.c (ext2fs_new_block): Fix fencepost error in
339 ext2fs_new_block; make sure we don't try to allocate the
340 first block beyond the end of the filesystem.
342 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
344 * inode.c (check_for_inode_bad_blocks): New function called by
345 get_next_blocks() to avoid reading in bad blocks marked in
346 fs->badblocks. Inodes located in bad blocks are returned
347 by ext2fs_get_next_inode() returns the error code
348 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
350 * alloc_tables.c (ext2fs_allocate_tables): New function which
351 performs the part of mke2fs's job of allocating the
354 * test_io.c (test_close): IO manager which is used for testing
357 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
359 * inode.c (ext2fs_get_next_inode): Separate out the function of
360 setting up for a new block group to get_next_blockgroup().
361 Separate out the function of reading in blocks of the
362 inode table to get_next_blocks().
364 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
366 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
367 blocks to the badblock list in sorted order. This allows
368 badblocks_list_test to be coded using a binary search for
371 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
373 * Release of E2fsprogs version 1.06

377 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
378 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
381 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
382 set, then only write out the master superblock.
384 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
386 * block.c (ext2fs_block_iterate): Fixed bug which caused
387 block_iterate to fail to handle HURD created filesystems;
388 it tested the inode translator field before the inode was
391 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
393 * initialize.c (ext2fs_initialize): Make sure the description for
394 the inode bitmap is set correctly.
396 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.

422 * namei.c (ext2fs_follow_link): New function.
423 (ext2fs_namei): Extended to have support for chasing
424 symbolic links. ext2fs_namei() still returns an inode
425 which is a symbolic link. Symbolic links are only chased
426 while resolving the containing directory. To chase
427 symbolic links of the final result, use
428 ext2fs_follow_link().
430 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
432 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
434 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines

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

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

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

536 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
537 to avoid conflicts with with kernel include files. Also
538 rename ADDR and CONST_ADDR to EXT2FS_ADDR and

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

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

633 file containing functions for reading and writing
634 directory blocks (byte swapping if necesssary)
636 * block.c (block_iterate_ind, block_iterate_dind,

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

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

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

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

748 * badblocks.c: Ditto.
752 * expanddir.c: Ditto.
753 * get_pathname.c: Ditto.
754 * initialize.c: Ditto.
761 * rw_bitmaps.c: Ditto.
764 * Makefile.in: Rewritten to conform to GNU coding standards and
765 support separate compilation directories.

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

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

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

828 magic number checking for the badblocks_list and
829 badblocks_iterate structures.
831 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):

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

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