Add support for EXT2_FEATURE_COMPAT_LAZY_BG
This feature 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.
Currently filefrag uses signed int for block numbers, thus it reporting
corrupted block number for a file on a more than 8TB ext3. The following
trivial patch replace the signed int type block number with "unsigned
long type.
Fix bug which could cause dumpe2fs to rarely fail to print a UUID
uuid.c (e2p_is_null_uuid): Fix really stupid bug which could cause dumpe2fs
to fail to display a the journal or hash seed UUID. (Thanks to Guillaume
Chambraud for pointing this out.)
This caused FTBFS bugs on AMD64 platforms, since it uses a different
64-bit type when compared with IA64, so we need to make our
autoconfiguration system more intelligent.
Fix ext2fs_add_journal_inode() when filesystem is opened in exclusive mode
If the filesystem is opened in exclusive mode, then device will be
busy by definition, so don't return -EBUSY. This caused mke2fs -j to
fail on the 1.39-WIP (29-Mar-2006) release. (Addresses Debian Bug:
#360652)
Let's call this an important wishlist bug (important for Debian Installer
anyway :-)
Please add the following line to the shlibs files for libblkid and libuuid
respectively:
udeb: libblkid 1 libblkid1-udeb
udeb: libuuid 1 libuuid1-udeb
This will allow dpkg/debhelper to properly set the dependencies for udebs
that depend on the e2fsprogs libs.
Please see #345472 and #345475 for further info on this.
This will also mean that, eventually, we will be able to drop the
"Provides: ..." for the library udebs, but we cannot do that until other
udebs that currently depend on them have been rebuilt.
I'll file a separate bug when that change can be made.

Fix the i386 bitmap operations so they are 32-bit clean
The x86 assembly instructures for bit test-and-set, test-and-clear,
etc., interpret the bit number as a 32-bit signed number, which is
problematic in order to support filesystems > 8TB.
Added new inline functions (in C) to implement a
ext2fs_fast_set/clear_bit() that does not return the old value of the
bit, and use it for the fast block/bitmap functions.
Added a regression test suite to test the low-level bit operations
functions to make sure they work correctly.
Note that a bitmap can address 2**32 blocks requires 2**29 bytes, or
512 megabytes. E2fsck requires 3 (and possibly 4 block bitmaps),
which means that the block bitmaps can require 2GB all by themselves,
and this doesn't include the 4 or 5 inode bitmaps (which assuming an
8k inode ratio, will take 256 megabytes each). This means that it's
more likely that a filesystem check of a filesystem greater than 2**31
blocks will fail if the e2fsck is dynamically linked (since the shared
libraries can consume a substantial portion of the 3GB address space
available to x86 userspace applications). Even if e2fsck is
statically linked, for a badly damaged filesystem, which may require
additional block and/or inode bitmaps, I am not sure e2fsck will
succeed in all cases.

Add device-mapper support to the blkid library
On systems where is multi-path storage device is problem with duplicated
filesystems. The solution is select "the best" device. This is possible

Short quotation from RH bugzilla:
With my patch, all dm devices remains in libblkid cache.
Only the top level dm devices are given high priority
and more appropriate node names (i.e. /dev/mapper/*) are used.
For example, if we have linear mapped dm device "ov1" over
dm device "disk1p3" which is multipath mapped to /dev/sdd3 and /dev/sdh3:
# dmsetup.static ls --tree
ov1 (253:5) <-- /dev/mapper/ov1 or /dev/dm-5
`-disk1p3 (253:4) <-- /dev/mapper/disk1p3 or /dev/dm-4
`-disk1 (253:0)
|- (8:112) <-- /dev/sdh
`- (8:48) <-- /dev/sdd

# ./orig/blkid -t LABEL=mpdisk1p3 -l

What's happening is that when you run on battery, e2fsck will delay
running the filesystem check, on the assumption that it is better to
defer the check until some time in the future when your laptop is
running on AC mains again. This deferral is not infinite, however; if
the number of mounts exceeds twice the max mount counts, or if the
interval between checks exceeds twice the check interval, e2fsck will
force the check even though you are on battery.
I've changed the sources to print a message to make this more clear.
