5  * Linux wait queue related types and methods
26  * A single wait-queue entry structure:
99  * returns true if the wait list is not empty
110  *      @cond = true;                     prepare_to_wait(&wq_head, &wait, state);
116  *                                      finish_wait(&wq_head, &wait);
120  * observe an empty wait list while the waiter might not observe @cond.
