3  * Generic wait-for-completion handler;
12  * Waiting for completion is a typically sync point, but not an exclusion point.
17  * complete: - signals a single thread waiting on this completion
18  * @x:  holds the state of this particular completion
20  * This will wake up a single thread waiting on this completion. Threads will be
28 void complete(struct completion *x)  in complete()
42  * complete_all: - signals all threads waiting on this completion
43  * @x:  holds the state of this particular completion
45  * This will wake up all threads waiting on this particular completion event.
50  * Since complete_all() sets the completion of @x permanently to done

234  * @x:  holds the state of this particular completion
236  * This waits to be signaled for completion of a specific task. It can be
