Message-Id: <20180322014413.24099-4-gniibe@fsij.org> Date: Thu, 22 Mar 2018 10:44:12 +0900 From: NIIBE Yutaka <gniibe@...j.org> To: linux-kernel@...r.kernel.org Cc: NIIBE Yutaka <gniibe@...j.org> Subject: [PATCH v2 3/4] signal/x86: Move restore_saved_sigmask(). Call to restore_saved_sigmask is only needed when it is from a system call. It is only woken up system call which uses saved_sigmask. Specifically, they are pselect, ppoll, and epoll_pwait.
