Kuniyuki Iwashima says:

====================
ip_tunnel: Support per-netns device unregistration.

Patch 1 - 3 are prep patches to unlink ip_tunnel device from
the hash table in ip_tunnel_dellink() only.

Patch 4 removes ip_tunnel_del() from ip_tunnel_uninit() to
ip_tunnel_dellink().

Patch 5 & 6 adds mutex to protect the per-netns hash table.

Patch 7 uses unregister_netdevice_queue_net() to support
cross-netns device unregistration.
