[v1,net-next,0/3] bareudp/pfcp/ppp: Improve netns dismantle.

pfcp and ppp holds RTNL in pernet_operations.exit(), which can be
converted to ->exit_batch_rtnl().  Patch 1 and 2 do the conversion.

bareudp leaves some unregistered devices in a list in dying netns
depending on where the device is cleaned up.  Patch 3 fixes that
inconsistency.


Kuniyuki Iwashima (3):
  pfcp: Convert pfcp_net_exit() to ->exit_batch_rtnl().
  ppp: Split ppp_exit_net() to ->exit_batch_rtnl().
  bareudp: Call bareudp_dellink() in bareudp_destroy_tunnels().
