NameDescribe
rt_mutex_slowlockSlow path lock function:
futex_lock_piUserspace tried a 0 -> TID atomic transition of the futex value* and failed. The kernel side here does the whole locking operation:* if there are waiters then it will block as a consequence of relying* on rt-mutexes, it does PI, etc
futex_wait_requeue_piex_wait_requeue_pi() - Wait on uaddr and take uaddr2*@uaddr: the futex we initially wait on (non-pi)*@flags: futex flags (FLAGS_SHARED, FLAGS_CLOCKRT, etc
