Subject: [PATCH 3/3] exit_state: kill task_is_dead()
Date: Wed, 13 Nov 2013 15:36:14 +0100 [thread overview]
Message-ID: <20131113143614.GA10547@redhat.com> (raw)
In-Reply-To: <20131113143552.GA10517@redhat.com>
task_is_dead() has no users since commit 43e13cc107cf
"cred: remove task_is_dead() from __task_cred() validation", and
nobody except exit.c should rely on ->exit_state (we still have
the users which should be changed).
