From f06c7f9f92295faf701a9628b383156c4efb6119 Mon Sep 17 00:00:00 2001 From: dingtianhong Date: Fri, 9 May 2014 14:58:05 +0800 Subject: [PATCH] vlan: rename __vlan_find_dev_deep() to __vlan_find_dev_deep_rcu() The __vlan_find_dev_deep should always called in RCU, according David's suggestion, rename to __vlan_find_dev_deep_rcu looks more reasonable.
