Merge branch 'for-3.5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj...

Pull cgroup fix from Tejun Heo:
 "This fixes the possible premature superblock release on umount bug
  mentioned during v3.5-rc1 pull request.

  Originally, cgroup dentry destruction path assumed that cgroup dentry
  didn't have any reference left after cgroup removal thus put super
  during dentry removal.  Now that there can be lingering dentry
  references, this led to super being put with live dentries.  This
  patch fixes the problem by putting super ref on dentry release instead
  of removal."
