E2fsprogs 1.20 (August 20, 2000 --- WORK IN PROGRESS)
=====================================================
Add support for replaying the ext3 journal purely in user mode. Used
code contributed by Andreas Dilger, with bug fixes by Theodore Ts'o.
E2fsck will now check for the existence of a linked list of orphan
inodes in the superblock, and clear those inodes before starting the
rest of the filesystem check (but after the journal playback).
Fixed bug in the progress bar printing code which could cause e2fsck
to core dump on an illegal filesystem.
Fsck using a UUID or a LABEL specifier will work even if devfs is
compiled into the kernel and not mounted. If the pathnames in
/proc/partitions are incorrect, fsck will search /dev for the correct
device (using the new ext2fs_find_block_device library function).
Fsck now also checks the RAID devices first so that they are properly
found when they are in use.
The dumpe2fs program can now print out the group description
information in hex, and also prints the location of the superblock and
block group descriptor for those block groups that have them.
Mke2fs now clears the ext2 superblock before it starts creating a
filesystem, so that the superblock magic number is only written if the
filesystem creation process successfully completes.
The debugfs program's stat command now pretty-prints the blocks used
by an inode so that it's more compact and informative.
The debugfs stats command now uses the same libe2p code (which is used
by dumpe2fs) to print the superblock header information. This is more
complete, and it avoids a bit of code duplication.
Added a new debugfs command, set_super_value (ssv) which allows the
user to set arbitrary superblock fields.
Programmer's notes:
-------------------
The e2fsck message printer now supports %Iu and %Ig, which will print
out the inode's user and group owners, respectively.
Added a new function to libext2, ext2fs_find_block_device(), which
searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
device given its device number.
Added new utility programs in tests/progs: random_exercise and
hold_inode. They aren't built by default; they're useful for
exercising ext3 filesystem code.
