Subject: [PATCH net-next-2.6] netfilter: remove synchronize_net() calls in ip_queue/ip6_queue
Date: Wed, 04 Nov 2009 20:47:35 +0100 [thread overview]
Message-ID: <4AF1DA57.8080202@gmail.com> (raw)
nf_unregister_queue_handlers() already does a synchronize_rcu()
call, we dont need to do it again in callers.
