1 Wed Sep 3 14:27:30 1997 Theodore Y. Ts'o <tytso@edt.mit.edu>
3 * llseek.c: Added missing semicolon to glibc fixup declaration of
6 * bmove.c: Add #include of errno.h
8 Sat Aug 23 22:47:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
10 * Makefile.in (ELF_SO_VERSION): Bump version to be 2.4 since we've
11 added a new field to the io_channel (app_data).
13 * io.h: Add a new element to the io_channel structure, app_data.
15 * initialize.c, openfs.c: Set io->app_data to point at the
18 Thu Aug 14 08:14:17 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
20 * io.h: Change the prototype of ext2fs_llseek() to use int's
21 instead of unsigned int's.
23 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
24 to make life easer for GNU Libc 2.
26 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
27 filesystem has its bitmaps stored as 32-bit words with bit
28 0 as the LSB of each word. Thus a bitmap with only bit 0
29 set would be, as a string of bytes, 00 00 00 01 00 ... To
30 cope with this, we byte-reverse each word of a bitmap if
31 we have a big-endian filesystem, that is, if we are *not*
32 byte-swapping other word-sized numbers.

98 test_io.c tst_badblocks.c tst_iscan.c unix_io.c unlink.c
99 valid_blk.c version.c: Add an #ifdef for HAVE_UNISTD_H
101 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
103 * unix_io.c (unix_read_blk): If ext2fs_llseek() fails, but errno
104 is zero, then return EXT2_IO_LLSEEK_FAILED.
106 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
108 * Release of E2fsprogs 1.11
110 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
112 * dblist.c (ext2fs_dblist_count): Added new function which returns
113 the number of directory blocks in dblist.
115 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
117 * unix_io.c (unix_flush): Make the io_channel flush function do a
118 fsync to flush the kernel buffers to disk.
120 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
122 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
123 current inode number wasn't being set by the
124 goto_blockgroup function.
126 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
128 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap
129 of blocks which need to be moved, and moves those blocks
130 to another location in the filesystem.
132 * rs_bitmap.c (ext2fs_resize_generic_bitmap): When expanding a
133 bitmap, make sure all of the new parts of the bitmap are
136 Sun Jun 8 16:24:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
138 * bitmaps.c (ext2fs_copy_bitmap): Fix bug; the destination bitmap
139 wasn't being returned to the caller.
141 * alloc_tables.c (ext2fs_allocate_group_table): Add new function
142 ext2fs_allocate_group_table() which sets the group tables
143 for a particular block group. The relevant code was
144 factored out of ext2fs_allocate_tables().
146 * dblist.c (make_dblist): Adjust the initial size of the directory
147 block list to be a bit more realistic (ten plus twice the
148 number of directories in the filesystem).
150 Thu May 8 22:19:09 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
152 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
153 ext2fs_badblocks_list_test would test the list (and exceed
154 array boundaries) if there were no bad blocks on the bad
155 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
157 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
159 * Release of E2fsprogs version 1.10
161 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
163 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
164 inode and block bitmaps based on the RAID 0 stride
165 parameter (which is passed by mke2fs).
167 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by
168 mke2fs to communicate the stride length to
169 ext2fs_allocate_tables()
171 Wed Apr 23 21:50:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
173 * initialize.c (ext2fs_initialize): Fix to compile under Linux 1.2
174 systems. (We can't assume that the new filesystem types
177 Wed Apr 23 18:40:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
179 * alloc_tables.c (ext2fs_allocate_tables): Make sure that we
180 allocate the inode and block bitmaps inside block group at
183 Mon Apr 21 00:06:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
185 * alloc.c (ext2fs_new_block): Fix bug where if goal==0 and the
186 filesystem has no free blocks, ext2fs_new_block would loop
189 * dupfs.c (ext2fs_dup_handle): Duplicate an ext2 filesystem handle
191 * freefs.c (ext2fs_free_inode_cache): Decrement refcount and only
192 free if refcount goes to zero.
194 * inode.c (create_icache): Initialize refcount to 1.
196 * ext2fsP.h: Added refcount to ext2_inode_cache
198 * dblist.c (ext2fs_copy_dblist): New function to copy a directory
201 * badblocks.c (ext2fs_badblocks_copy): New function to copy a

208 * unix_io.c, test_io.c (unix_open, test_open): Initialize the
210 (unix_close, test_close): Decrement the refcount and only
211 close the io_channel if the refcount goes to 0.
213 * io.h: Add refcount to the io_channel structure. Add new macro
214 interface io_channel_bumpcount() to bump the refcount.
216 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
218 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
219 cache in the filesystem handle, instead of the inode cache
220 in a static variable.
222 * freefs.c: Added static function to free the inode cache (called by
225 * ext2fsP.h: Added definition of the ext2_inode_cache structures.
227 * ext2fs.h: Added pointer to the inode_cache structure.
229 * block.c (block_iterate_ind, block_iterate_dind,
230 block_iterate_tind): If there are holes in the indirect,
231 doubly indirect, or triply indirect blocks, increment the
232 block count field automatically.
234 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
236 * Release of E2fsprogs version 1.09
238 Mon Apr 14 20:38:56 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
240 * version.c (ext2fs_parse_version_string): Check the passed in
241 version string (instead of the hard-coded one).
243 * alloc_tables.c (ext2fs_allocate_tables): If the last block is
244 greater filesystem size, clamp it to prevent allocating a
245 block or inode bitmap beyond the filesystem.
247 * initialize.c (ext2fs_initialize): Fix bug where the metatdata
248 overhead calculation was accidentally removed.
250 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
252 * Release of E2fsprogs version 1.08
254 Thu Apr 10 13:15:15 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
256 * dblist.c (ext2fs_set_dir_block): New function which sets the
257 block of a dblist entry, given the directory inode and
260 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
262 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
263 inode bitmaps at staggered locations across the block
264 groups, to avoid concentrating the bitmaps on a small
265 number of disks when using striped RAID arrays.
267 * initialize.c (ext2fs_initialize): By default, choose the maximum
268 possible number of blocks per group (based on the size of
269 the bitmaps in the blocksize).
271 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
273 * initialize.c (ext2fs_initialize): Add support for
274 EXT2_COMPAT_SPARSE_SUPER feature.
276 * closefs.c (ext2fs_bg_has_super): New function to determine
277 whether or a particular block group should have a
278 superblock and block group descriptor. Used for the
279 EXT2_COMPAT_SPARSE_SUPER feature is turned on.
280 (ext2fs_flush): Check ext2fs_bg_has_super to see whether
281 or not the superblock should be written out for the block
284 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
285 for sparse duplicate superblocks.
287 * version.c (ext2fs_get_library_version): New function which
288 returns the library version.
290 * version.c (ext2fs_parse_version_string): New function which
291 parses a version string and returns a version number,
292 so application programs can compare version numbers as
295 Wed Mar 26 00:43:52 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
297 * icount.c (ext2fs_create_icount): Change function so that it also
298 takes a new argument which contains a "hint" icount
299 structure. This "hint" icount allows the create function
300 to set up the sorted list in advance. This reduces
301 significantly the amount of data moving needed to insert
302 these inodes into the list later.
304 * icount.c (ext2fs_icount_validate): New function which validates
305 that the icount structure's rep invariant.
307 * icount.c (get_icount_el): Completely revamped implementation
308 to subsume put_icount_el(). Put_icount_el() used to
309 use an O(N) implementation to insert in the middle
310 of the icount list. It now uses a O(ln N) to search
311 for where the icount should be inserted, and then uses
312 a memcpy to move the list down (instead of a for loop).
314 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
315 ext2fs_icount_increment, ext2fs_icount_decrement): Check
316 to see if the inode is within bounds; if it isn't, return
319 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
320 when a bad inode number is passed to test_generic_bitmap
321 to be EXT2FS_TEST_ERROR instead of the wrong
324 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
326 * Release of E2fsprogs version 1.07
328 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
330 * Makefile.in (ELF_VERSION): Change version to be 2.2
332 Tue Feb 11 14:54:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
334 * alloc.c (ext2fs_get_free_blocks): Change routine to use
335 ext2fs_fast_test_block_bitmap_range().
337 * bitops.h (ext2fs_fast_test_block_bitmap_range,
338 ext2fs_test_block_bitmap_range: New inline functions which
339 test to see whether a contiguous range of blocks is
342 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
344 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
345 use ext2fs_badblocks_* instead of badblocks_*
347 * bb_compat.c: New file which translates between old badblocks_*()
348 names to ext2fs_badblocks_*()
350 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
351 link.c (since e2fsck doesn't use ext2fs_unlink()).
353 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
354 bitmap resizing routine moved from bitmaps.c, since e2fsck
355 doesn't need to use this function.
357 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
358 since e2fsck only needs ext2fs_lookup.
360 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
362 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
363 already set; this is needed so that programs like dump
364 which use the inode scan functions will deal with
365 filesystems that have bad blocks in the inode table.
367 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
369 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
370 Moved to ext2fsP.h, since it doesn't need to be part of
371 the public interface.
373 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
375 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
377 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
378 directory block list abstraction. (Code moved from
381 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
382 to inode.c (since no one else should be peeking inside it!)
384 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
386 * openfs.c (ext2fs_open): Check the feature set in the ext2
387 superblock, and refuse to open filesystems if they contain
388 incompatible features. (Can be overriden with the
391 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
393 * block.c (ext2fs_block_iterate2): Added new function
394 ext2fs_block_iterate2 which changes the function
395 signature of the callback function to include the
396 referencing block and offset.
398 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
399 ext2fs_inode_scan_goto_blockgroup which allows an
400 application to jump to a particular block group while
403 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
405 * dirblock.c: Include string.h, since we use memcpy().
407 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
409 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
410 a long not an int; this doesn't matter on i386 machines,
411 but it does on Alpha's.
413 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
415 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
416 table pointer is NULL, then return an error indicating
417 that the inode table is missing.
418 (get_next_blockgroup, get_next_blocks,
419 ext2fs_get_next_inode): Don't treat a missing inode table
420 as permanent error. Return MISSING_INODE_TABLE, but as an
421 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
423 * rw_bitmaps.c (ext2fs_write_block_bitmap,
424 ext2fs_write_inode_bitmap): If the inode or block bitmap
425 block is zero, then don't write out the inode or block
426 bitmap. The idea here is to avoid stomping on the
428 (read_bitmaps): If the inode or block bitmap block is
429 zero, then fill in that portion of the inode or block
430 bitmap with all zeros.
432 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
433 blocks in inode table when the inode table size is
434 non-standard (and can therefore span blocks).
436 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
438 * alloc.c (ext2fs_new_block): Fix fencepost error in
439 ext2fs_new_block; make sure we don't try to allocate the
440 first block beyond the end of the filesystem.
442 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
444 * inode.c (check_for_inode_bad_blocks): New function called by
445 get_next_blocks() to avoid reading in bad blocks marked in
446 fs->badblocks. Inodes located in bad blocks are returned
447 by ext2fs_get_next_inode() returns the error code
448 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
450 * alloc_tables.c (ext2fs_allocate_tables): New function which
451 performs the part of mke2fs's job of allocating the
454 * test_io.c (test_close): IO manager which is used for testing
457 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
459 * inode.c (ext2fs_get_next_inode): Separate out the function of
460 setting up for a new block group to get_next_blockgroup().
461 Separate out the function of reading in blocks of the
462 inode table to get_next_blocks().
464 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
466 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
467 blocks to the badblock list in sorted order. This allows
468 badblocks_list_test to be coded using a binary search for
471 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
473 * Release of E2fsprogs version 1.06
475 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
477 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
478 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
481 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
482 set, then only write out the master superblock.
484 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
486 * block.c (ext2fs_block_iterate): Fixed bug which caused
487 block_iterate to fail to handle HURD created filesystems;
488 it tested the inode translator field before the inode was
491 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
493 * initialize.c (ext2fs_initialize): Make sure the description for
494 the inode bitmap is set correctly.
496 * bitmaps.c (ext2fs_allocate_generic_bitmap): Fix minor type typo.
498 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
500 * Release of E2fsprogs version 1.05
502 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
504 * initialize.c: Override the kernel's idea of default
505 checkinterval from 0 (never) to 180 days.
507 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
509 * namei.c (ext2fs_namei_follow): New function which follows
510 symbolic link (if any) at the target.

514 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
515 for shortcut function fs->read_inode() and fs->write_inode().
516 Added inode_cache to reduce CPU time spent in doing
519 * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
522 * namei.c (ext2fs_follow_link): New function.
523 (ext2fs_namei): Extended to have support for chasing
524 symbolic links. ext2fs_namei() still returns an inode
525 which is a symbolic link. Symbolic links are only chased
526 while resolving the containing directory. To chase
527 symbolic links of the final result, use
528 ext2fs_follow_link().
530 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
532 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
534 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines

556 * block.c (ext2fs_block_iterate): Cause block iterator to return
557 the HURD translator block (along with everything else).
558 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
559 iterator, then don't return any meta data blocks
560 (including the HURD translator).
562 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

696 Move these functions to freefs.c.
698 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
699 descriptors shadow memory to keep purify quiet. (This
700 also has the nice benefit that the unused portion of the
701 shadow descriptors are zeroed out.)
703 * dirblock.c (ext2fs_write_dir_block): We need to use
704 dirent->rec_len *before* it's byteswapped to find the
705 location of the next directory structure!
707 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
708 cause ext2fs_new_inode to loop infinitely if we're trying
709 to allocate an inode in group #0 and there are no free
710 inodes at all in the system.

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

783 * block.c (block_iterate_ind, block_iterate_dind,
784 block_iterate_tind): Don't recompute block_nr each loop;

787 variable out of the loop. (block_iterate_ind, in
788 particular, gets called a lot, so every little
791 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>

810 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
811 instead of llseek. The errno if the offset is too large
812 and lseek is not supported should be EINVAL, not -EINVAL.

816 * Makefile.in: Added support for ELF shared libraries.
817 Fixed typos in the compilation rules.
818 (distclean): Added Makefile.
820 * llseek.c (llseek): New function, if llseek() does not exist in the
822 (ext2_llseek): Changed to call llseek().
824 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
826 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
828 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
830 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
832 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
833 the S_*, which are normally defined in <sys/stat.h>. This
834 allows us to compile e2fsprogs on a non-Linux system,
835 which may have a different value for S_IFDIR.
837 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
839 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();
840 this is a user-mode application!
842 Thu Jun 8 13:13:22 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
844 * llseek.c: Put the include of <linux/unistd.h> inside the #ifdef

881 * unix_io.c (unix_open): Initialize the read_error and write_error
882 io_channel pointers to be null.
884 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
885 found, clear it but don't try to update the filesystem
886 accounting information, since that's hopeless anyway.
888 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
889 bloblock_iterate_tind): Check to see if the indirect blocks are
890 valid before trying to read them.
892 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
893 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.

897 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
898 illegal block or inode number is passed in, return instead
899 of trying to test, set, or clear the bit.
901 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>

973 someone uses the -b option to specify the use of the backup
974 superblock --- this usually means that the main superblock is
978 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
979 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
980 revision level to the superblock.

989 * initialize.c: Completely revamped the inode and block bitmap
990 structures, so that they can be better chance of being extensible
991 in a shared library. They are now their own type, instead of
992 being a char *. Also, the function signatures of
993 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
994 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
995 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
996 changed to eliminate the ext2_filsys argument, since it is no

1001 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1002 system call if available.

1013 the group descriptor statistics in addition to everything else.
1014 This relieves mke2fs of the responsibility of doing it.
1016 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1017 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1018 not the generic C function equivalents should be included or not.
1020 * openfs.c (ext2fs_open): If a superblock is specified, then use
1021 the backup group descriptors that go along with this superblock,
1022 instead of using the primary group descriptors. This allows
1023 e2fsck to recover filesystems where the primary group descriptors
