[GIT PULL] ext4 bug fixes

["Theodore Ts'o" <tytso@mit.edu>]

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!!
