Subject: [PATCH 2/2] wait: allow sys_waitid() to use __WNOTHREAD/__WCLONE/__WALL
Date: Tue, 20 Oct 2015 19:17:59 +0200 [thread overview]
Message-ID: <20151020171759.GA29311@redhat.com> (raw)
In-Reply-To: <20151020171740.GA29290@redhat.com>
I see no reason why waitid() can't support other linux-specific flags
allowed in sys_wait4().
