revert "cancel_delayed_work: use del_timer() instead of del_timer_sync()"

223a10a9 · Oleg Nesterov <[email protected]> · 2007-05-18 00:36:42 -07:00

As pointed out by Jarek Poplawski, the patch

	[WORKQUEUE]: cancel_delayed_work: use del_timer() instead of del_timer_sync()
	commit: 071b638689464c6b39407025eedd810d5b5e6f5d

was wrong, it was merged by mistake after that.

From the changelog:

	after this patch:
		...
		delayed_work_timer_fn->__queue_work() in progress.

		The latter doesn't differ from the caller's POV,

it does make a difference if the caller calls flush_workqueue() after
cancel_delayed_work(), in that case flush_workqueue() can miss this
work_struct.
