SRU Justification
Impact:
The following patches are heading to the stable maintainers tree and will eventually get pulled into
the
Lucid tree. The earlier we can get these in the fewer issues our users will encounter. We will be getting
these through stable-tree updates, we would just be pulling them in a little earlier.
The following patches should really be applied to the Lucid 2.6.32-22.33 kernel:
ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/ext4-patches/ext4-patches-for-2.6.32.11--14.tar.gz
There is a git tree you may find useful here:
git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git lucid-2.6.32-ext4
It fixes a very large number of ext4 bugs, including (but not limited to):
http://bugzilla.kernel.org/show_bug.cgi?id=14286
http://bugzilla.kernel.org/show_bug.cgi?id=14936
http://bugzilla.kernel.org/show_bug.cgi?id=15420
http://bugzilla.kernel.org/show_bug.cgi?id=15579

http://bugzilla.kernel.org/show_bug.cgi?id=15792
http://bugzilla.kernel.org/show_bug.cgi?id=15827
This patch has been submitted upstream, but I'm not sure if Greg K-H will be doing another 2.6.32.y kernel release.
Testing:
TBD
