Subject[git patches] ocfs2 fixes
Hi Linus,
Here's some more Ocfs2 patches for 2.6.24. This series also includes
a small performance fixup from Jan Kara. The rest of the patches are bug
fixes or very trivial cleanups.

Please pull from 'upstream-linus' branch of
git://git.kernel.org/pub/scm/linux/kernel/git/mfasheh/ocfs2.git upstream-linus

to receive the following updates:
