Type:void

Parameter:

Type	Parameter	Name
struct rt_mutex *	lock

1641

raw_spin_lock_irqsave( & wait_lock, flags)

1642

postunlock = Futex variant, that since futex variants do not use the fast-path, can be* simple and will not need to retry.

1643

raw_spin_unlock_irqrestore( & wait_lock, flags)

1645

If postunlock Then Performs the wakeup of the the top-waiter and re-enables preemption.

**Caller**
Name	Describe
futex_lock_pi	Userspace 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_pi	ex_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
