Subject: [PATCH net-next 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.
I'm not intializing vlgrp to null before kfree_rcu because Ido has a patch
for that which fixes a warning from kasan.
Patch 03 fixes a bug reported by Ido Schimmel about the vlan_flush order
and switchdevs, and patch 04 refactors (br|nbp)_vlan_flush and combines
them into a single function.

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: break vlan_flush in two phases to keep old order
  bridge: vlan: combine (br|nbp)_vlan_flush into one
