Subject: [PATCH 6/7] ipvs: remove extra rcu lock
Date: Wed, 20 Mar 2013 11:49:33 +0100 [thread overview]
Message-ID: <1363776574-4766-7-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1363776574-4766-1-git-send-email-pablo@netfilter.org>
From: Julian Anastasov <ja@ssi.bg>
In 3.7 we added code that uses ipv4_update_pmtu but after commit
c5ae7d4192 (ipv4: must use rcu protection while calling fib_lookup)
the RCU lock is not needed.
