From a1f5315ce4e1700e65255c617561aa7d8f09a729 Mon Sep 17 00:00:00 2001 From: Gao Feng Date: Wed, 7 Dec 2016 12:23:18 +0800 Subject: [PATCH] driver: macvlan: Remove the rcu member of macvlan_port When free macvlan_port in macvlan_port_destroy, it is safe to free directly because netdev_rx_handler_unregister could enforce one grace period. So it is unnecessary to use kfree_rcu for macvlan_port. Signed-off-by: Gao Feng Signed-off-by: David S.
