- * struct completion - structure used to maintain state for a "completion"
- *
- * This is the opaque structure used to maintain the state for a "completion".
- * Completions currently use a FIFO to queue threads that have to wait for
- * the "completion" event.
- *
- * See also:  complete(), wait_for_completion() (and friends _timeout,
- * _interruptible, _interruptible_timeout, and _killable), init_completion(),
- * reinit_completion(), and macros DECLARE_COMPLETION(),
- * DECLARE_COMPLETION_ONSTACK().
