+
+ * pass4.c (pass4): If the user refuses to connect an unattached
+ inode to lost+found, don't try to set i_links_count. This
+ is bad, since if the user says yes, the inode will be
+ marked as unused, which is not necessarily the right
+ thing, especially since the rest of the cleanup doesn't
+ happen here.
+
+ * pass2.c (deallocate_inode): Set inode_link_info[ino] when
+ dellocating an inode. (Not strictly necessary, but...)
+
+ * pass4.c (pass4): Add "bonehead" explanation to the "programming
+ error" message.
+
+Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * e2fsck.c (PRS,main): Added new options -s and -S. -s will
+ byte-swap the filesystem so that it is normalized. -S
+ will byte-swap the filesystem regardless of its current
+ byte-order.
+
+ * swapfs.c: New file, which will byte-swap a filesystem.
+
+Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * pass1.c (pass1): Change handling on files with non-zero dtime
+ and non-zero i_link_count; before we treated them as
+ deleted file per botched ext2 0.3c kernel behavior. We
+ now clear dtime instead.
+
+Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * e2fsck.c (main): If e2fsck sets the clean bit, even if
+ nothing else is changed, make sure FSCK_NONDESTRUCT is
+ set (since after all having the filesystem set to
+ invalid is an error. :-)
+
+Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * pass1.c (process_block): Make sure that meta data doesn't get
+ accidentally set in the dir_blocks array (which could
+ happen in some error condtions).
+
+ * pass1.c (pass1):
+ * pass2.c (process_bad_inode): Check for fragments in a
+ OS-independent fashion.
+
+Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * e2fsck.c (check_if_skip): Close the filesystem when skipping the
+ cleanup for the filesystem.
+
+Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>

+ fsetversion.c, fsetflags.c, fgetversion.c, fgetflags.c,
+ getflags.c: Remove include of ext2_fs.h, since it's
+ included by e2p.h; this also solves a sys/types.h vs
+ linux/types.h inclusion ordering problem with the GNU libc.

+
+ * initialize.c: Override the kernel's idea of default
+ checkinterval from 0 (never) to 180 days.
+
+Wed Aug 28 03:20:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * namei.c (ext2fs_namei_follow): New function which follows
+ symbolic link (if any) at the target.
+
+Tue Aug 27 01:48:43 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * inode.c (ext2fs_read_inode, ext2fs_write_inode): Add support
+ for shortcut function fs->read_inode() and fs->write_inode().
+ Added inode_cache to reduce CPU time spent in doing
+ byte swapping.
+
+ * swapfs.c (ext2fs_swap_super): Swap the new fields in a V2
+ superblock.
+
+ * namei.c (ext2fs_follow_link): New function.
+ (ext2fs_namei): Extended to have support for chasing
+ symbolic links. ext2fs_namei() still returns an inode
+ which is a symbolic link. Symbolic links are only chased
+ while resolving the containing directory. To chase
+ symbolic links of the final result, use
+ ext2fs_follow_link().
+
+Mon Aug 26 23:46:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2_err.et.in: Added new error code EXT2_ET_SYMLINK_LOOP.
+
+ * bitops.h (ext2fs_set_bit, ext2fs_celar_bit): Use asm inlines
+ provided by Pete A. Zaitcev (zaitcev@lab.sun.mcst.ru).
+
+Thu Aug 22 00:40:18 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * initialize.c (ext2fs_initialize): On systems where the byte
+ order is not i386 compatible, set the swap_byte flag.
+
+ * inode.c (inocpy_with_swap): Check to see if inode contains a
+ fast symlink before swapping the inode block fields. This
+ required adding a new argument to inocpy_with_swap to
+ determine whether the mode field is in host order or not.
+
+Wed Aug 21 00:45:42 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * bitops.h (ext2fs_set_bit, ext2fs_clear_bit, ext2fs_test_bit): On
+ the sparc, if EXT2_STD_BITOPS set, use the standard
+ i386-compatible bitmask operations, instead on the
+ non-standard native bitmask operators.
+
+Fri Aug 9 11:11:35 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * block.c (ext2fs_block_iterate): Cause block iterator to return
+ the HURD translator block (along with everything else).
+ If the flag BLOCK_FLAG_DATA_ONLY is passed to the block
+ iterator, then don't return any meta data blocks
+ (including the HURD translator).
+
+Wed Jul 17 17:13:34 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * gen_uuid.c: New file, which generates DCE-compatible UUIDs.
+
+ * uuid.c: New file, containing UUID utility functions.
+
+Tue Jul 16 10:19:16 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2fs.h: Add a definition of the "real" ext2 superblock.
+
+Fri May 24 14:54:55 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * ext2fs.h: Fix erroneous ino_t type used in block_bitmap type.
+
+Sun May 19 15:39:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
+
+ * openfs.c (ext2fs_open): If the blocksize in the superblock is
+ zero, return the error EXT2_ET_CORRUPT_SUPERBLOCK, since
+ that's a basic value that must be correct for the rest of
+ the library to work.
+
+ * ext2_err.et.in (EXT2_ET_CORRUPT_SUPERBLOCK): Added new error
