Sorry, I could not look at these patches before...

So I think this one should be reverted, it makes PTRACE_EVENT_EXIT even more broken.

Once again, why we can't do something like

	--- x/kernel/signal.c
	+++ x/kernel/signal.c
	@@ -209,6 +209,8 @@ int next_signal(struct sigpending *pendi
		 */
		x = *s &~ *m;
		if (x) {
	+		if (x & sigmask(SIGKILL))
	+			return SIGKILL;
			if (x & SYNCHRONOUS_MASK)
				x &= SYNCHRONOUS_MASK;
			sig = ffz(~x) + 1;

instead? at least for the start.

Oleg.
