2021-06-22selftests: futex: Add futex compare requeue testAndré Almeida1-0/+136
Add testing for futex_cmp_requeue(). The first test just requeues from one waiter to another one, and wakes it. The second performs both wake and requeue, and checks the return values to see if the operation woke/requeued the expected number of waiters.
