  There's inconsistency with some wakeups between using rreq->waitq (a private
  waitqueue) and using clear_and_wake_up_bit() (a shared global waitqueue).
  The reason I didn't get round to posting the patches on this branch yet is
  that they *ought* to fix the problem, but Steve French still sees an
  occasional hang with cifs - but only in his automated testing thing, and we
  haven't tracked it down yet.
