8  * Atomic wait-for-completion handler data structures.
9  * See kernel/sched/completion.c for details.
15  * struct completion - structure used to maintain state for a "completion"
17  * This is the opaque structure used to maintain the state for a "completion".
19  * the "completion" event.
26 struct completion {
32 static inline void complete_acquire(struct completion *x) {}
33 static inline void complete_release(struct completion *x) {}
45  * DECLARE_COMPLETION - declare and initialize a completion structure
46  * @work:  identifier for the completion structure
48  * This macro declares and initializes a completion structure. Generally used
53 	struct completion work = COMPLETION_INITIALIZER(work)
61  * DECLARE_COMPLETION_ONSTACK - declare and initialize a completion structure
62  * @work:  identifier for the completion structure
64  * This macro declares and initializes a completion structure on the kernel
69 	struct completion work = COMPLETION_INITIALIZER_ONSTACK(work)
71 	struct completion work = COMPLETION_INITIALIZER_ONSTACK_MAP(work, map)
78  * init_completion - Initialize a dynamically allocated completion
79  * @x:  pointer to completion structure that is to be initialized
81  * This inline function will initialize a dynamically created completion
84 static inline void init_completion(struct completion *x)
91  * reinit_completion - reinitialize a completion structure
92  * @x:  pointer to completion structure that is to be reinitialized
94  * This inline function should be used to reinitialize a completion structure so it can
