block_all_signals() must die (Was: Patch for lost wakeups)

[Oleg Nesterov]

And sorry for off-topic email, but I can't resist.

Can't we finally kill block_all_signals() and ->notifier ? This
is very, very wrong and doesn't work anyway.

I tried to ask many, many times. Starting from 2007 at least.
And every time the discussion "hangs". I am quoting the last
email I sent below.

Dave, your reply was:

	 I'm on
	 holidays for another week or so, maybe once I get back I'll find some
	 time to figure out how it works vs what happens, but really I suspect
	 we can kill this with fire.

So perhaps I should simply send the patch with your ack? ;)

Oleg.
