[GIT PULL] ext4 bug fixes

[Theodore Ts'o]

Hi Linus,

Please pull from:

        git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4.git for_linus

This patch series contains a number of bug fixes that fixes various
BUG() crashes discovered by early adopters for ext4 and by benchmarkers.
I'd really like to get these fixes included for 2.6.27.

Thanks!!

Since commit 7d455e0030eeab820773e7786605be4d9e56a04b this is already
done in common code, so this changeset doesn't have any effect.

Hmm, I thought Andrew said he this was better to do in each filesystem
rather than in the common code, so I thought he was NACK'ing that
patch.  Still, I see his sign-off, so I guess I must have misread the
thread.....
