78 Fri Nov 28 09:26:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
80 * dblist.c (ext2fs_get_num_dirs): Make ext2fs_get_num_dirs more
81 paranoid about validating the directory counts from the
82 block group information.
84 * all files: Don't include stdlib.h anymore; include it in
85 ext2_fs.h, since that file requires stdlib.h

209 * llseek.c: Change to allow PIC and !HAVE_LLSEEK. Add a prototype
210 to make life easer for GNU Libc 2.
212 * rw_bitmaps.c: On the PowerPC, the big-endian variant of the ext2
213 filesystem has its bitmaps stored as 32-bit words with bit
214 0 as the LSB of each word. Thus a bitmap with only bit 0
215 set would be, as a string of bytes, 00 00 00 01 00 ... To
216 cope with this, we byte-reverse each word of a bitmap if
217 we have a big-endian filesystem, that is, if we are *not*
218 byte-swapping other word-sized numbers.

292 * ext2_err.et.in: Add a new error code, EXT2_IO_LLSEEK_FAILED.
294 * Release of E2fsprogs 1.11
296 Mon Jun 16 23:53:06 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

299 the number of directory blocks in dblist.
301 Sat Jun 14 01:39:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
303 * unix_io.c (unix_flush): Make the io_channel flush function do a
304 fsync to flush the kernel buffers to disk.
306 Wed Jun 11 18:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
308 * inode.c (ext2fs_inode_scan_goto_blockgroup): Fix bug; the
309 current inode number wasn't being set by the
310 goto_blockgroup function.
312 Mon Jun 9 10:45:48 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
314 * bmove.c (ext2fs_move_blocks): New function which takes a bitmap

338 * badblocks.c (ext2fs_badblocks_list_test): Fix bug where
339 ext2fs_badblocks_list_test would test the list (and exceed
340 array boundaries) if there were no bad blocks on the bad
341 blocks list. (Showed up when user tried: mke2fs -c -b 4096).
343 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
345 * Release of E2fsprogs version 1.10
347 Thu Apr 24 10:13:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
349 * alloc_tables.c (ext2fs_allocate_tables): Correctly place the
350 inode and block bitmaps based on the RAID 0 stride
351 parameter (which is passed by mke2fs).
353 * ext2fs.h: Add "stride" parameter to ext2_filsys, to be used by

396 (unix_close, test_close): Decrement the refcount and only
397 close the io_channel if the refcount goes to 0.
399 * io.h: Add refcount to the io_channel structure. Add new macro
400 interface io_channel_bumpcount() to bump the refcount.
402 Thu Apr 17 20:25:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
404 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Use the inode
405 cache in the filesystem handle, instead of the inode cache
406 in a static variable.

443 block of a dblist entry, given the directory inode and
446 Sat Apr 5 12:42:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
448 * alloc_tables.c (ext2fs_allocate_tables): Allocate the bitmap and
449 inode bitmaps at staggered locations across the block
450 groups, to avoid concentrating the bitmaps on a small
451 number of disks when using striped RAID arrays.
453 * initialize.c (ext2fs_initialize): By default, choose the maximum
454 possible number of blocks per group (based on the size of
455 the bitmaps in the blocksize).
457 Fri Apr 4 11:28:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
459 * initialize.c (ext2fs_initialize): Add support for
460 EXT2_COMPAT_SPARSE_SUPER feature.
462 * closefs.c (ext2fs_bg_has_super): New function to determine

467 or not the superblock should be written out for the block
470 * ext2fs.h (EXT2_COMPAT_SPARSE_SUPER): Define compatibility flag
471 for sparse duplicate superblocks.

483 * icount.c (ext2fs_create_icount): Change function so that it also
484 takes a new argument which contains a "hint" icount
485 structure. This "hint" icount allows the create function
486 to set up the sorted list in advance. This reduces
487 significantly the amount of data moving needed to insert
488 these inodes into the list later.
490 * icount.c (ext2fs_icount_validate): New function which validates
491 that the icount structure's rep invariant.
493 * icount.c (get_icount_el): Completely revamped implementation
494 to subsume put_icount_el(). Put_icount_el() used to
495 use an O(N) implementation to insert in the middle
496 of the icount list. It now uses a O(ln N) to search
497 for where the icount should be inserted, and then uses
498 a memcpy to move the list down (instead of a for loop).
500 * icount.c (ext2fs_icount_fetch, ext2fs_icount_store,
501 ext2fs_icount_increment, ext2fs_icount_decrement): Check
502 to see if the inode is within bounds; if it isn't, return
505 * bitops.h (ext2fs_test_generic_bitmap): Fix error message given
506 when a bad inode number is passed to test_generic_bitmap
507 to be EXT2FS_TEST_ERROR instead of the wrong
510 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
512 * Release of E2fsprogs version 1.07
514 Sun Mar 2 16:46:18 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>

520 * alloc.c (ext2fs_get_free_blocks): Change routine to use
521 ext2fs_fast_test_block_bitmap_range().

525 test to see whether a contiguous range of blocks is
528 Thu Feb 6 10:00:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
530 * badblocks.c (ext2fs_badblocks_list_create): Rename sybmols to use
531 use ext2fs_badblocks_* instead of badblocks_*
533 * bb_compat.c: New file which translates between old badblocks_*()
534 names to ext2fs_badblocks_*()
536 * unlink.c (ext2fs_unlink): New file, moved ext2fs_unlink() from
537 link.c (since e2fsck doesn't use ext2fs_unlink()).
539 * rs_bitmap.c (ext2fs_resize_generic_bitmap): New file, contains
540 bitmap resizing routine moved from bitmaps.c, since e2fsck
541 doesn't need to use this function.
543 * lookup.c (ext2fs_lookup): Moved ext2fs_lookup to its own file,
544 since e2fsck only needs ext2fs_lookup.
546 Mon Feb 3 10:11:40 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
548 * inode.c (ext2fs_open_inode_scan): Set fs->badblocks if it is not
549 already set; this is needed so that programs like dump
550 which use the inode scan functions will deal with
551 filesystems that have bad blocks in the inode table.
553 Sun Feb 2 00:17:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
555 * ext2fs.h (struct_badblocks_list, struct_badblocks_iterate):
556 Moved to ext2fsP.h, since it doesn't need to be part of
557 the public interface.
559 * dir_iterate.c: Move ext2_dir_iterate out of namei.c.
561 Sat Feb 1 10:14:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
563 * dblist.c (ext2fs_get_num_dirs): New file, which implements a
564 directory block list abstraction. (Code moved from
567 * ext2fs.h, inode.c: Moved definition of ext2_struct_inode_scan to
568 to inode.c (since no one else should be peeking inside it!)
570 * valid_blk.c (ext2_inode_has_valid_blocks): New function.
572 * openfs.c (ext2fs_open): Check the feature set in the ext2
573 superblock, and refuse to open filesystems if they contain
574 incompatible features. (Can be overriden with the
577 Sun Jan 12 11:31:46 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
579 * block.c (ext2fs_block_iterate2): Added new function
580 ext2fs_block_iterate2 which changes the function
581 signature of the callback function to include the
582 referencing block and offset.
584 * inode.c (ext2fs_inode_scan_goto_blockgroup): Added new function
585 ext2fs_inode_scan_goto_blockgroup which allows an
586 application to jump to a particular block group while
589 Wed Jan 1 23:50:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
591 * dirblock.c: Include string.h, since we use memcpy().
593 Tue Dec 3 12:27:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
595 * getsize.c (ext2fs_get_device_size): The ioctl BLKGETSIZE returns
596 a long not an int; this doesn't matter on i386 machines,
597 but it does on Alpha's.
599 Fri Nov 29 20:57:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
601 * inode.c (ext2fs_write_inode, ext2fs_read_inode): If the inode
602 table pointer is NULL, then return an error indicating
603 that the inode table is missing.
604 (get_next_blockgroup, get_next_blocks,
605 ext2fs_get_next_inode): Don't treat a missing inode table
606 as permanent error. Return MISSING_INODE_TABLE, but as an
607 advisory error code, much like BAD_BLOCK_IN_INODE_TABLE.
609 * rw_bitmaps.c (ext2fs_write_block_bitmap,
610 ext2fs_write_inode_bitmap): If the inode or block bitmap
611 block is zero, then don't write out the inode or block
612 bitmap. The idea here is to avoid stomping on the
614 (read_bitmaps): If the inode or block bitmap block is
615 zero, then fill in that portion of the inode or block
616 bitmap with all zeros.
618 * inode.c (ext2fs_get_next_inode): Fix bug in handling of bad
619 blocks in inode table when the inode table size is
620 non-standard (and can therefore span blocks).
622 Tue Oct 29 20:13:14 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
624 * alloc.c (ext2fs_new_block): Fix fencepost error in
625 ext2fs_new_block; make sure we don't try to allocate the
626 first block beyond the end of the filesystem.
628 Mon Oct 14 11:00:48 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
630 * inode.c (check_for_inode_bad_blocks): New function called by
631 get_next_blocks() to avoid reading in bad blocks marked in
632 fs->badblocks. Inodes located in bad blocks are returned
633 by ext2fs_get_next_inode() returns the error code
634 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE.
636 * alloc_tables.c (ext2fs_allocate_tables): New function which
637 performs the part of mke2fs's job of allocating the
640 * test_io.c (test_close): IO manager which is used for testing
643 Sun Oct 13 04:31:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
645 * inode.c (ext2fs_get_next_inode): Separate out the function of
646 setting up for a new block group to get_next_blockgroup().
647 Separate out the function of reading in blocks of the
648 inode table to get_next_blocks().
650 * ext2fs.h: Add the badblocks list to the ext2_filsys entry
652 * badblocks.c (badblocks_list_add, badblocks_list_test): Add
653 blocks to the badblock list in sorted order. This allows
654 badblocks_list_test to be coded using a binary search for
657 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
659 * Release of E2fsprogs version 1.06
661 Mon Oct 7 00:44:17 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
663 * ext2fs.h, block.c, closefs.c, dirblock.c, inode.c, native.c,
664 open.c: Change EXT2_SWAP to EXT2_FLAG_SWAP for
667 * closefs.c (ext2fs_flush): If the flag EXT2_MASTER_SB_ONLY is
668 set, then only write out the master superblock.
670 Sun Oct 6 21:45:26 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
672 * block.c (ext2fs_block_iterate): Fixed bug which caused
673 block_iterate to fail to handle HURD created filesystems;
674 it tested the inode translator field before the inode was
677 Tue Sep 17 14:08:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
679 * initialize.c (ext2fs_initialize): Make sure the description for

686 * Release of E2fsprogs version 1.05
688 Sat Sep 7 07:36:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
690 * initialize.c: Override the kernel's idea of default
691 checkinterval from 0 (never) to 180 days.
693 Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
695 * namei.c (ext2fs_namei_follow): New function which follows
696 symbolic link (if any) at the target.

700 * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
701 for shortcut function fs->read_inode() and fs->write_inode().

708 * namei.c (ext2fs_follow_link): New function.
709 (ext2fs_namei): Extended to have support for chasing
710 symbolic links. ext2fs_namei() still returns an inode
711 which is a symbolic link. Symbolic links are only chased
712 while resolving the containing directory. To chase
713 symbolic links of the final result, use
714 ext2fs_follow_link().
716 Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
718 * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
720 * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
721 provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
723 Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
725 * initialize.c (ext2fs_initialize): On systems where the byte
726 order is not i386 compatible, set the swap_byte flag.
728 * inode.c (inocpy_with_swap): Check to see if inode contains a
729 fast symlink before swapping the inode block fields. This
730 required adding a new argument to inocpy_with_swap to
731 determine whether the mode field is in host order or not.
733 Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
735 * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
736 the sparc, if EXT2_STD_BITOPS set, use the standard
737 i386-compatible bitmask operations, instead on the
738 non-standard native bitmask operators.
740 Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
742 * block.c (ext2fs_block_iterate): Cause block iterator to return
743 the HURD translator block (along with everything else).
744 If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
745 iterator, then don't return any meta data blocks
746 (including the HURD translator).
748 Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
750 * gen_uuid.c: New file, which generates DCE-compatible UUIDs.

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

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

822 Rename {test,set,clear}_bit to ext2fs_{test,set,clear}_bit,
823 to avoid conflicts with with kernel include files. Also
824 rename ADDR and CONST_ADDR to EXT2FS_ADDR and
827 Thu Oct 26 12:09:16 1995 <tytso@rsts-11.mit.edu>
829 * ext2_err.et: Updated message in EXT2_ET_BASE to say version 0.5c
831 * swapfs.c (ext2fs_swap_super): Put an #ifdef check around
832 s_def_resuid and s_def_resgid for backwards compatibility.
834 Fri Oct 20 23:33:31 1995 <tytso@rsts-11.mit.edu>

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

881 * bitmaps.c (ext2fs_free_inode_bitmap, ext2fs_free_block_bitmap):
882 Move these functions to freefs.c.
884 * closefs.c (ext2fs_flush): If swapping blocks, clear the group
885 descriptors shadow memory to keep purify quiet. (This
886 also has the nice benefit that the unused portion of the
887 shadow descriptors are zeroed out.)
889 * dirblock.c (ext2fs_write_dir_block): We need to use
890 dirent->rec_len *before* it's byteswapped to find the
891 location of the next directory structure!
893 * alloc.c (ext2fs_new_inode): Fix bug which could potentially
894 cause ext2fs_new_inode to loop infinitely if we're trying
895 to allocate an inode in group #0 and there are no free
896 inodes at all in the system.
898 * closefs.c: #include <errno.h> if it exists.
900 Sun Aug 6 13:27:50 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>

929 Call inocpy_with_swap if EXT2_SWAP_BYTES if set.
931 * closefs.c (ext2fs_flush): If EXT2_SWAP_BYTES is set, then swap
932 the superblock and group descriptors before writing it out.
934 * openfs.c (ext2fs_open): If the magic number is byte-swapped,
935 then set the EXT2_SWAP_BYTES and byte-swap the superblock

939 to desp ext2 filesystem structures.
941 * bitops.c (set_bit, clear_bit, test_bit): Use modifications
942 supplied by Pete A. Zaitcev so that the C language
943 versions of these functions are more portable. They will
944 now work on both little and big endian systems, and the
945 assumption that 32-bit integers are used is gone.
947 * bitops.h (ext2_swab16, ext2_swab32): Added new functions for
950 * ext2fs.h (EXT2_SWAP_BYTES): Add new flag which indicates that
951 byte swapping should take place.

964 * inode.c (ext2fs_get_next_inode): Don't check scan->inode_buffer;
965 if the magic number is correct, it will be allocated.
967 Fri Jul 14 19:02:59 1995 <tytso@rsx-11.mit.edu>
969 * block.c (block_iterate_ind, block_iterate_dind,
970 block_iterate_tind): Don't recompute block_nr each loop;
971 just increment it! Factor check of BLOCK_FLAG_APPEND out
972 of the loop. Factor mask of BLOCK_CHANGED into changed
973 variable out of the loop. (block_iterate_ind, in
974 particular, gets called a lot, so every little
977 Thu Jul 13 08:02:45 1995 <tytso@rsx-11.mit.edu>
979 * block.c (block_iterate_ind, block_iterate_dind,

985 ext2fs_fast_mark_inode_bitmap, ext2fs_fast_unmark_inode_bitmap,
986 ext2fs_fast_test_inode_bitmap): Add fast version of these
987 functions, which don't do range checking.
989 * bitops.h (ext2fs_get_block_bitmap_start,
990 ext2fs_get_inode_bitmap_start, ext2fs_get_block_bitmap_end,
991 ext2fs_get_inode_bitmap_end): Add new accessor functions
992 which return the start and end points of the bitmaps.
994 Tue Jul 11 18:59:41 1995 <tytso@rsx-11.mit.edu>
996 * llseek.c (ext2_llseek): If the offset is small enough, use lseek
997 instead of llseek. The errno if the offset is too large
998 and lseek is not supported should be EINVAL, not -EINVAL.
1000 Thu Jun 15 23:43:02 1995 Remy Card <card@bbj>
1002 * Makefile.in: Added support for ELF shared libraries.
1003 Fixed typos in the compilation rules.
1004 (distclean): Added Makefile.
1006 * llseek.c (llseek): New function, if llseek() does not exist in the
1008 (ext2_llseek): Changed to call llseek().
1010 Mon Jun 12 08:29:07 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1012 * ext2fs.h: Use __u32 to define blk_t, instead of unsigned long.
1014 Sun Jun 11 15:02:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1016 * mkdir.c (ext2fs_mkdir): Use LINUX_S_IFDIR instead of S_IFDIR.
1018 * ext2fs.h (LINUX_S_IFDIR): Define a linux specific versions of
1019 the S_*, which are normally defined in <sys/stat.h>. This
1020 allows us to compile e2fsprogs on a non-Linux system,
1021 which may have a different value for S_IFDIR.
1023 Sat Jun 10 23:47:05 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1025 * bitops.c (clear_bit, set_bit): Remove calls to cli() and sti();

1051 support separate compilation directories.
1053 Thu May 11 04:13:12 1995 <tytso@rsx-11.mit.edu>
1055 * initialize.c (ext2fs_initialize): Don't allow more than one
1056 bitmaps's worth of inodes in a group.
1058 Sat Mar 11 14:07:11 1995 Theodore Y. Ts'o <tytso@localhost>
1060 * llseek.c (ext2_llseek): Added error checking to the llseek()
1061 compat code to protect against overflow. This only
1062 applies to 1.0 and early 1.1 kernels, which don't support
1063 the llseek() system call.
1065 Thu Nov 24 16:29:00 1994 Theodore Y. Ts'o (tytso@rt-11)
1067 * unix_io.c (unix_open): Initialize the read_error and write_error
1068 io_channel pointers to be null.
1070 * bb_inode.c (clear_bad_block_proc): If an illegal block number is
1071 found, clear it but don't try to update the filesystem
1072 accounting information, since that's hopeless anyway.
1074 * block.c (bloblock_iterate_ind, bloblock_iterate_dind,
1075 bloblock_iterate_tind): Check to see if the indirect blocks are
1076 valid before trying to read them.
1078 * ext2_err.et (EXT2_ET_BAD_IND_BLOCK, EX2_ET_BAD_DIND_BLOCK,
1079 EXT2_ET_BAD_TIND_BLOCK): Add new error codes.
1081 * bitops.h (ext2fs_mark_block_bitmap, ext2fs_unmark_block_bitmap,
1082 ext2fs_test_block_bitmap, ext2fs_mark_inode_bitmap,
1083 ext2fs_unmark_inode_bitmap, ext2fs_test_inode_bitmap): If an
1084 illegal block or inode number is passed in, return instead
1085 of trying to test, set, or clear the bit.
1087 Mon Nov 7 21:32:33 1994 Remy Card <card@bbj>
1089 * Makefile: Added a dummy install target in case shared libraries
1092 Mon Oct 24 14:11:44 1994 (tytso@rsx-11)
1094 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix calculation of how
1095 the real last block of the bitmap should be calculated.
1097 Wed Sep 7 10:05:36 1994 (tytso@rsx-11)
1099 * bitmaps.c (ext2fs_fudge_inode_bitmap_end,
1100 ext2fs_fudge_block_bitmap_end, ext2fs_clear_inode_bitmap,
1101 ext2fs_clear_block_bitmap, ext2fs_free_inode_bitmap,
1102 ext2fs_free_block_bitmap): Add magic number checking for
1103 the inode and block bitmaps.
1105 * bitmaps.c (ext2fs_allocate_block_bitmap): Fix to set the correct
1106 magic number for a block bitmap instead of an inode bitmap.
1108 * inode.c (ext2fs_close_inode_scan, ext2fs_get_next_inode): Add
1109 magic number checking for the inode_scan structure.
1111 * badblocks.c (badblocks_list_free, badblocks_list_add,
1112 badblocks_list_test, badblocks_list_iterate_begin,
1113 badblocks_list_iterate, badblocks_list_iterate_end): Add
1114 magic number checking for the badblocks_list and
1115 badblocks_iterate structures.
1117 * ext2_err.et (EXT2_ET_MAGIC_UNIX_IO_CHANNEL):
1118 * unix_io.c (unix_open, unix_close, unix_set_blksize, unix_read_blk,

1120 both for io_channel structure and unix_private_data
1123 * openfs.c (ext2fs_open): Add check for io_manager structure's
1126 * rw_bitmaps.c (ext2fs_write_inode_bitmap, ext2fs_write_block_bitmap,
1127 ext2fs_read_inode_bitmap, ext2fs_read_block_bitmap,
1128 ext2fs_read_bitmaps, ext2fs_write_bitmaps):
1129 * read_bb.c (ext2fs_read_bb_inode):
1130 * read_bb_file.c (ext2fs_read_bb_FILE):
1131 * newdir.c (ext2fs_new_dir_block):

1134 * inode.c (ext2fs_open_inode_scan, ext2fs_read_inode,
1135 ext2fs_write_inode, ext2fs_get_blocks,
1136 ext2fs_check_directory):

1141 ext2fs_allocate_block_bitmap):
1142 * bb_inode.c (ext2fs_update_bb_inode):
1143 * alloc.c (ext2fs_new_inode,ext2fs_new_block,ext2fs_get_free_blocks):

1155 structure magic numbers.
1157 * closefs.c (ext2fs_flush): Folded in Remy Card's changes to clear
1158 the EXT2_VALID_FS flag in the backup superblock blocks, so that if
1159 someone uses the -b option to specify the use of the backup
1160 superblock --- this usually means that the main superblock is
1164 * ext2_err.et (EXT2_ET_REV_TOO_HIGH):
1165 * openfs.c (ext2fs_open): Folded in Remy Card's changes to add a
1166 revision level to the superblock.
1168 Sun Aug 21 00:50:08 1994 Theodore Y. Ts'o (tytso@rt-11)
1175 * initialize.c: Completely revamped the inode and block bitmap
1176 structures, so that they can be better chance of being extensible
1177 in a shared library. They are now their own type, instead of
1178 being a char *. Also, the function signatures of
1179 ext2fs_test_block_bitmap, ext2fs_mark_block_bitmap,
1180 ext2fs_unmark_block_bitmap, ext2fs_test_inode_bitmap,
1181 ext2fs_mark_inode_bitmap, and ext2fs_unmark_inode_bitmap were
1182 changed to eliminate the ext2_filsys argument, since it is no
1185 Wed Aug 17 21:46:44 1994 Remy Card (card@bbj)
1187 * unix_io.c (unix_read_blk and unix_write_blk): use the llseek
1188 system call if available.
1190 * llseek.c: new file. This is the stub calling the llseek system
1191 call which allows supports for 2GB+ file systems.
1193 * initialize.c (ext2fs_initialize): Ext2fs_initialize now stores
1194 the creator operating system.
1196 Wed Aug 17 10:03:24 1994 Theodore Y. Ts'o (tytso@rt-11)
1198 * initialize.c (ext2fs_initialize): Ext2fs_initialize now sets up
1199 the group descriptor statistics in addition to everything else.
1200 This relieves mke2fs of the responsibility of doing it.
1202 * bitops.c, bitops.h: Add assembly inline functions for the 68000.
1203 Added a new #define, _EXT2_HAVE_ASM_BITOPS_ to control whether or
1204 not the generic C function equivalents should be included or not.
1206 * openfs.c (ext2fs_open): If a superblock is specified, then use
1207 the backup group descriptors that go along with this superblock,
1208 instead of using the primary group descriptors. This allows
1209 e2fsck to recover filesystems where the primary group descriptors
