Merge branch 'for_linus_urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 bugfix from Ted Ts'o.

[ Hmm.  It's possible we should make kfree() aware of error pointers,
  and use IS_ERR_OR_NULL rather than a NULL check.  But in the meantime
  this is obviously the right fix.  - Linus ]
