E2fsprogs 1.39-WIP (April 9, 2006)
E2fsprogs 1.39-WIP (May 14, 2006)
===================================
Dumpe2fs will now print the size of the journal (if present).
Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
between 2**31 and 2**32 blocks.
Fix mklost+found so that it creates a full-sized directory on
filesystems with larger block sizes.
Fix a file descriptor leak in blkid library.
Change mke2fs to use /etc/mke2fs.conf as a configuration file to
configure the filesystem features, blocksize, and inode_ratio for
different filesystem types.

Fixed a bug in mke2fs which caused it to to fail when creating the
resize inode for large filesystems. (Addresses Debian Bug #346580)
When allocating space for the RAID filesystems with the stride
parameter, mke2fs will now place each portion of the group's inode
table right up after the superblock (if present) in order to minimize
fragmentation of the freespace.
Speed up mke2fs and e2fsck by writing inode and block bitmaps more
efficiently by writing the inode and block bitmaps in one pass, thus
reducing the number of disk seeks required.
Add support for on-line resizing to resize2fs.

E2fsck will stop and print a warning if the user tries running a
read/write badblocks test on a read-only mounted root filesystem.
Fix a memory leak in e2fsck's error paths. (Thanks to Michael
C. Thompson for pointing these out; they were originally found using
Coverity.)
When resizing a file containing a filesystem, resize2fs will expand or
truncate a file as necessary. (Addresses Debian Bug: #271607)
Resize2fs will now automatically determine the RAID stride parameter that
had been used to create the filesystem, and use that for newly created
block groups. The RAID stride parameter may also be manually specified
on the command line using the new -S option to resize2fs.
Fix mke2fs so that it correctly creates external journals on
big-endian machines (such as a S/390).
Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
fail to print out the journal or hash seed UUID. (Thanks to Guillaume
Chambraud for pointing this out.)
Dumpe2fs will now print the size of the journal (if present).
Fix debugfs's set_inode_field command so it can properly set the frag,
fsize, uid_high, gid_high, and author fields in the inode instead of
silently failing, and so that setting the i_size actually sets i_size

Sourceforge Bug #1261549)
Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
intended for testing purposes. It allows an ext2/ext3 developer to
create very large filesystems using sparse files where most of the
block groups are not initialized and so do not require much disk
space. Eventually it could be used as a way of speeding up mke2fs and
e2fsck for large filesystem, but that would be best done by adding an
RO_COMPAT extension to the filesystem to allow the inode table to be
lazily initialized on a per-block basis, instead of being entirely
initialized or entirely unused on a per-blockgroup basis.
