Date: Fri, 23 Jan 2009 15:00:29 +0200 From: Rémi Denis-Courmont <remi.denis-courmont@...ia.com> To: netdev@...r.kernel.org Subject: [PATCH 5/6] Phonet: remove useless locking in device cleanup Incoming packets and sockets are already gone. The netdevice notifier is unregistered under the RTNL lock There remains a race with the rtnetlink handlers unregistration, but it is a generic RTNL issue that was already present before this change.
