The following commit has been merged in the master branch: commit a06ee256e5d6f03fffbd088de9bf84035658cc5a Merge: bd6207202db8974ca3d3183ca0d5611d45b2973c 846e8dd47c264e0b359afed28ea88e0acdee6818 Author: David S. Miller <davem(a)davemloft.net> Date: Tue Sep 25 10:35:29 2018 -0700 Merge ra.kernel.org:/pub/scm/linux/kernel/git/davem/net Version bump conflict in batman-adv, take what's in net-next. iavf conflict, adjustment of netdev_ops in net-next conflicting with poll controller method removal in net.
