Message-Id: <1313071035-12047-34-git-send-email-matt@console-pimps.org> Date: Thu, 11 Aug 2011 14:57:07 +0100 From: Matt Fleming <matt@...sole-pimps.org> To: Oleg Nesterov <oleg@...hat.com> Cc: linux-kernel@...r.kernel.org, Chris Zankel <chris@...kel.net> Subject: [PATCH 33/41] xtensa: Don't reimplement force_sigsegv() From: Matt Fleming <matt.fleming@...el.com> Instead of open coding the sequence from force_sigsegv() just call it. This also fixes a race because sa_handler was being modified without holding ->sighand->siglock.
