Proto:long wait_woken(struct wait_queue_entry *wq_entry, unsigned mode, long timeout)

Type:long

Parameter:

Type	Parameter	Name
struct wait_queue_entry *	wq_entry	>flags &= ~WQ_FLAG_WOKEN; ~~~~~~~~~~~~~~~~~~
unsigned	mode
long	timeout

431

set_current_state(mode)

432

If Not (flags & WQ_FLAG_WOKEN) && Not is_kthread_should_stop() Then timeout = schedule_timeout - sleep until timeout*@timeout: timeout value in jiffies* Make the current task sleep until @timeout jiffies have* elapsed

434

set_current_state() includes a barrier so that the write of current->state* is correctly serialised wrt the caller's subsequent test of whether to* actually sleep:* for (;;) {* set_current_state(TASK_UNINTERRUPTIBLE);* if (!need_sleep)* break;* (Used in tsk->state: )

smp_store_mb(flags, flags & ~WQ_FLAG_WOKEN)

444

Return timeout
