<div class='commit-subject'>Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace</div><div class='commit-msg'>Pull namespace fix from Eric Biederman:
 "This has a single brown bag fix.

  The possible deadlock with dec_pid_namespaces that I had thought was
  fixed earlier turned out only to have been moved. So instead of being
  cleaver this change takes ucounts_lock with irqs disabled. So
  dec_ucount can be used from any context without fear of deadlock.

  The items accounted for dec_ucount and inc_ucount are all
  comparatively heavy weight objects so I don't exepct this will have
  any measurable performance impact"
