Log Message:
The return values for FUTEX_REQUEUE and FUTEX_CMP_REQUEUE are different,
but we weren't doing to the right thing.
FUTEX_REQUEUE returns the number of waiters awakened.
FUTEX_CMP_REQUEUE returns the number of waiters awakenend plus the
number of waiters requeued (and it is an exercise for the caller to
calculate the number requeued, if it cares).
