  extend completions to provide XFS object flush requirements
  XFS object flushing doesn't quite match existing completion semantics.  It
  mixed exclusive access with completion.  That is, we need to mark an object as
  being flushed before flushing it to disk, and then block any other attempt to
  flush it until the completion occurs.  We do this but adding an extra count to
  the completion before we start using them.  However, we still need to
  determine if there is a completion in progress, and allow no-blocking attempts
  fo completions to decrement the count.
  To do this we introduce:
  int try_wait_for_completion(struct completion *x)
  returns a failure status if done == 0, otherwise decrements done
  to zero and returns a "started" status. This is provided
  to allow counted completions to begin safely while holding
  object locks in inverted order.
  int completion_done(struct completion *x)
  returns 1 if there is no waiter, 0 if there is a waiter
  (i.e. a completion in progress).
  This replaces the use of semaphores for providing this exclusion
  and completion mechanism.
