Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec-next
Steffen Klassert says: ==================== ipsec-next 2016-09-08 1) Constify the xfrm_replay structures. From Julia Lawall 2) Protect xfrm state hash tables with rcu, lookups can be done now without acquiring xfrm_state_lock. From Florian Westphal. 3) Protect xfrm policy hash tables with rcu, lookups can be done now without acquiring xfrm_policy_lock. From Florian Westphal. 4) We don't need to have a garbage collector list per namespace anymore, so use a global one instead. From Florian Westphal. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
