Use kfree_rcu() directly. 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
