Subject: [PATCH net-next v2 0/4] bridge: vlan: cleanups & fixes (part 3)

From: Nikolay Aleksandrov <nikolay@...ulusnetworks.com>

Hi,
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

Thank you,
 Nik

Nikolay Aleksandrov (4):
  bridge: vlan: use proper rcu for the vlgrp member
  bridge: vlan: use rcu for vlan_list traversal in br_fill_ifinfo
  bridge: vlan: drop unnecessary flush code
  bridge: vlan: move back vlan_flush
