From 0d7dd798fd89d986a6c59030b704827a4e6a13b4 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 9 Jun 2016 07:45:15 -0700 Subject: [PATCH] net: ipvlan: call netdev_lockdep_set_classes() In case a qdisc is used on a ipvlan device, we need to use different lockdep classes to avoid false positives. Use the new netdev_lockdep_set_classes() generic helper. Signed-off-by: Eric Dumazet Signed-off-by: David S.
