netns xfrm: xfrm6_tunnel in netns
I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
(as it should), and unregistering involves rcu barriers by itself
So it looks nothing should be done.
