[PATCH 0/3] delayed_work tweaks

[Oleg Nesterov <oleg@tv-sign.ru>]

Andrew, unless you stop me right now, I am going to send the following
patches in addition:

	[PATCH] kill cancel_rearming_delayed_workqueue()

		cancel_rearming_delayed_workqueue(wq, dwork) does not
		need the first parameter, it could be figured out from
		dwork. So we can rename it to cancel_rearming_delayed_work
		after the simple change and fix all callers.

		In other words:

			- cancel_rearming_delayed_work(dwork) will work
			  for any workqueue, not just keventd_wq.

			- all callers of cancel_rearming_delayed_workqueue()
			  will be converted to use it.

		No? This breaks the public interface, but we already did
		this recently ...

	[PATCH] kill flush_work_keventd()

		The same is true for flush_work(), it doesn't need the
		"struct workqueue_struct *wq" parameter. I missed this
		fact when I was doing flush_work().

		This change is obviously good to do before flush_work()
		goes to mainline.

		Also, I think the name "flush_work" is very bad. Isn't
		it better to rename it as well?

		cancel_work? cancel_work_sync? whatever.

	[PATCH] bonus: mark kernel/workqueue.c as CONFIG_EXPERIMENTAL

		too many non-reviewed changes ...

Oleg.
