名称描述
queue_mequeue_me() - Enqueue the futex_q on the futex_hash_bucket*@q: The futex_q to enqueue*@hb: The destination hash bucket* The hb->lock must be held by the caller, and is released here. A call to
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
