Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull namespace updates from Eric Biederman:
 "This is a set of small fixes that were mostly stumbled over during
  more significant development. This proc fix and the fix to
  posix-timers are the most significant of the lot.

  There is a lot of good development going on but unfortunately it
  didn't quite make the merge window"
