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

Pull proc fix from Eric Biederman:
 "Much to my surprise syzbot found a very old bug in proc that the
  recent changes made easier to reproce. This bug is subtle enough it
  looks like it fooled everyone who should know better"
