Lines Matching full:set

8  * - FREE -> SET (qemu_event_set)
9  * - BUSY -> SET (qemu_event_set)
10  * - SET -> FREE (qemu_event_reset)
14  * BUSY -> SET and FREE -> BUSY, respectively.
16  * Without futex, BUSY -> SET and FREE -> BUSY never happen. Instead, the waking
17  * operation follows FREE -> SET and the blocking operation will happen in
18  * qemu_event_wait() if the event is not SET.
20  * SET->BUSY does not happen (it can be observed from the outside but
21  * it really is SET->FREE->BUSY).
23  * busy->free provably cannot happen; to enforce it, the set->free transition
145              * set or busy.  in qemu_event_wait()
158          * This is the final check for a concurrent set, so it does need  in qemu_event_wait()
