Date: Thu, 13 Sep 2018 14:54:21 +0200	[thread overview]
Message-ID: <20180913125450.21342-20-jolsa@kernel.org> (raw)
In-Reply-To: <20180913125450.21342-1-jolsa@kernel.org>

Adding thread::exited to indicate the thread has exited,
and keeping the thread::dead flag to indicate thread
is on the dead list.
