Message-Id: <1361008406-2307-4-git-send-email-msb@chromium.org> Date: Sat, 16 Feb 2013 01:53:25 -0800 From: Mandeep Singh Baines <msb@...omium.org> To: linux-kernel@...r.kernel.org Cc: Mandeep Singh Baines <msb@...omium.org>, Oleg Nesterov <oleg@...hat.com>, Tejun Heo <tj@...nel.org>, Andrew Morton <akpm@...ux-foundation.org>, "Rafael J. Wysocki" <rjw@...k.pl>, Ingo Molnar <mingo@...hat.com> Subject: [PATCH 4/5] freezer: clear fake signal on exit from __refrigerator In freeze_task, a freeze request is sent as a fake signal. Recalculate signal pending on exit from __refrigerator so that TIF_SIGPENDING doesn't remain incorrectly set.
