Subject: [RFC PATCH v2 0/7] signal: sigprocmask fixes
Date: Mon, 18 Apr 2011 15:44:21 +0200	[thread overview]
Message-ID: <20110418134421.GA15951@redhat.com> (raw)

Andrew, please drop V1:

	signal-introduce-retarget_shared_pending.patch
	signal-retarget_shared_pending-consider-shared-unblocked-signals-only.patch
	signal-sigprocmask-narrow-the-scope-of-sigloc.patch
	signal-sigprocmask-should-do-retarget_shared_pending.patch
	x86-signal-handle_signal-should-use-sigprocmask.patch
	x86-signal-sys_rt_sigreturn-should-use-sigprocmask.patch

Changes in V2:

	- 2/7 change retarget_shared_pending() to accept mask, not ~mask

	- 3/7 is new, it adds the optimization promised in 2/7

	- 4/7 add the small comment about current->blocked as Matt
	      suggested

	- 5/7 add the new helper, set_current_blocked(), suggested
	      by Linus

	- 8/7 is the new and a bit off-topic cleanup, but sys_rt_sigprocmask()
	      looks so annoying

Matt, I didn't dare to keep your reviewed-by tags because of the
changes above, hopefully you can re-ack.

Once again: if we need this, then we need a lot more (trivial) changes
like 6/7 and 7/7. Basically every change of ->blocked should be converted
to use set_current_blocked(). OTOH, perhaps this makes sense by itself.

Oleg.
