Biederman" , Pavel Emelyanov , Robert Rex , Roland McGrath , Serge Hallyn , Sukadev Bhattiprolu , linux-kernel@vger.kernel.org Subject: [PATCH 3/4] pid_ns: de_thread: kill the now unneeded ->child_reaper change Message-ID: <20080824154912.GA3783@tv-sign.ru> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.11 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1018 Lines: 26 de_thread() checks if the old leader was the ->child_reaper, this is not possible any longer. With the previous patch ->group_leader itself will change ->child_reaper on exit. >From now find_new_reaper() is the only function (apart from initialization) which plays with ->child_reaper.
