From 4e4c22c71144c1b2e22c257ec6cf08ccb5be1165 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Apr 2008 00:53:06 -0700 Subject: signals: add set_restore_sigmask This adds the set_restore_sigmask() inline in and replaces every set_thread_flag(TIF_RESTORE_SIGMASK) with a call to it. No change, but abstracts the details of the flag protocol from all the calls.
