[ Upstream commitfbf4dec702] Observed occassional failures in the futex_wait_timeout test: ok 1 futex_wait relative succeeds ok 2 futex_wait_bitset realtime succeeds ok 3 futex_wait_bitset monotonic succeeds ok 4 futex_wait_requeue_pi realtime succeeds ok 5 futex_wait_requeue_pi monotonic succeeds not ok 6 futex_lock_pi realtime returned 0 ...... The test expects the child thread to complete some steps before the parent thread gets to run. There is an implicit expectation of the order of invocation of futex_lock_pi between the child thread and the parent thread. Make this order explicit. If the order is not met, the futex_lock_pi call in the parent thread succeeds and will not timeout.
