====================
pull request (net-next): ipsec-next 2016-09-23

Only two patches this time:

1) Fix a comment reference to struct xfrm_replay_state_esn.
   From Richard Guy Briggs.

2) Convert xfrm_state_lookup to rcu, we don't need the
   xfrm_state_lock anymore in the input path.
   From Florian Westphal.

Please pull or let me know if there are problems.
