Subject: Re: [PATCH] x86_64: fix delayed signals

In-Reply-To: <alpine.LFD.1.10.0807111031310.2936@woody.linux-foundation.org> (Linus Torvalds's message of "Fri, 11 Jul 2008 10:58:54 -0700 (PDT)")
Linus Torvalds <torvalds@linux-foundation.org> writes:
Linus, the fact that is not explained by your theory is why
Ctrl-Z+kill works but Ctrl-C doesn't. On the signal side these
both should be implemented in the same way -- if there was
really a missing signal_pending() check somewhere then Ctrl-Z
(and kill) should be delayed too.
Now doing faster signal processing is always a good thing in general,
but I'm a little doubtful your patch will help with that
particular problem.
