Applied and squashed into single patch for netfilter these patches:

[17/17] netfilter: xt_hashlimit: replace call_rcu by kfree_rcu for simple kmem_cache_free callback
[16/17] netfilter: expect: replace call_rcu by kfree_rcu for simple kmem_cache_free callback
[15/17] netfilter: nf_conncount: replace call_rcu by kfree_rcu for simple kmem_cache_free callback

this update is now flying to net-next.

Thanks
