* Because of non-atomic nature of operations performed sequentially on the futex
* counter and the futex wait queue, there is a race condition:
*
* wq->missed_wakeups == 1 && futex->count = 1
* (wq->missed_wakeups == 1) && (futex->count = 1)
*
* Scenario 1 (wait queue timeout vs. futex_up()):
* 1. assume wq->missed_wakeups == 0 && futex->count == -1
