Message-Id: <1313772419-21951-37-git-send-email-matt@console-pimps.org> Date: Fri, 19 Aug 2011 17:46:52 +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 v2 36/43] 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 bug because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]), whereas the intention of the code was to modify sighand->action[] directly. As the original code was working with a copy it had no effect on signal delivery.
