pull request (net-next): ipsec-next 2015-05-28
1) Remove xfrm_queue_purge as this is the same as skb_queue_purge.
2) Optimize policy and state walk.
3) Use a sane return code if afinfo registration fails.
4) Only check fori a acquire state if the state is not valid.
5) Remove a unnecessary NULL check before xfrm_pol_hold
as it checks the input for NULL.
6) Return directly if the xfrm hold queue is empty, avoid
to take a lock as it is nothing to do in this case.
7) Optimize the inexact policy search and allow for matching
of policies with priority ~0U.
All from Li RongQing.
Please pull or let me know if there are problems.
