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.
