Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to net, ixgbe and e1000e. David provides compiler fixes for e1000e. Don provides a fix for ixgbe to resolve a compile warning. John provides a fix to net where it is useful to be able to walk all upper devices when bringing a device online where the RTNL lock is held. In this case, it is safe to walk the all_adj_list because the RTNL lock is used to protect the write side as well. This patch adds a check to see if the RTNL lock is held before throwing a warning in netdev_all_upper_get_next_dev_rcu(). ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
