Merge tag 'interrupting_kthread_stop-for-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace

Pull kthread update from Eric Biederman:
 "Break out of wait loops on kthread_stop()

  This is a small tweak to kthread_stop so it breaks out of
  interruptible waits, that don't explicitly test for kthread_stop.

  These interruptible waits occassionaly occur in kernel threads do to
  code sharing"
