207 Every mutex keeps track of all the waiters that are blocked on itself. The mutex
208 has a plist to store these waiters by priority. This list is protected by
218 a list of all top waiters of the mutexes that are owned by the process.
219 Note that this list only holds the top waiters and not all waiters that are
322 in more detail, but is set whenever there are waiters on a mutex.
375 waiters of all the mutexes that the task owns, rt_mutex_getprio simply needs
585 be false, because if the mutex has no owner, there are no waiters and
586 the current task also won't have any waiters. But we don't have the lock
615 means that if the mutex doesn't have any waiters, there's no accounting needed
