I just want to make sure you saw this change in net-next:

====================
commit ca065d0cf80fa547724440a8bf37f1e674d917c0
Author: Eric Dumazet <edumazet@...gle.com>
Date:   Fri Apr 1 08:52:13 2016 -0700

    udp: no longer use SLAB_DESTROY_BY_RCU
====================

Does that effect your change?
