Merge branch 'bridge-vlan'
Nikolay Aleksandrov says: ==================== bridge: vlan: cleanups & fixes (part 3) Patch 01 converts the vlgrp member to use rcu as it was already used in a similar way so better to make it official and use all the available RCU instrumentation. Patch 02 fixes a bug where the vlan_list can be traversed without rtnl or rcu held which could lead to using freed entries. Patch 03 removes some redundant code that isn't needed anymore. Patch 04 fixes a bug reported by Ido Schimmel about the vlan_flush order and switchdevs, it moves it back. v2: patch 03 and 04 are new, couldn't escape the second synchronize_rcu() since the rhtable destruction can sleep ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
