====================
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.
