Subject: [PATCH] fork.c: cleanup for copy_sighand()
Date: Fri, 31 Oct 2008 16:51:19 +0800	[thread overview]
Message-ID: <490AC707.1060808@cn.fujitsu.com> (raw)

Check CLONE_SIGHAND only is enough, because combination of CLONE_THREAD and
CLONE_SIGHAND is already done in copy_process().

Impact: cleanup, no functionality changed
