Date: Mon, 2 Sep 2013 13:51:42 +0200 From: Nikolay Aleksandrov <nikolay@...hat.com> To: netdev@...r.kernel.org Cc: andy@...yhouse.net, fubar@...ibm.com, davem@...emloft.net Subject: [PATCH net-next 5/5] bonding: drop read_lock in bond_compute_features bond_compute_features is always called with RTNL held, so we can safely drop the read bond->lock.
