Date: Mon, 5 Sep 2016 12:58:19 +0200 [thread overview]
Message-ID: <1473073124-5015-5-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1473073124-5015-1-git-send-email-pablo@netfilter.org>
From: Florian Westphal <fw@strlen.de>
... so we don't need to touch all of these places when we get rid of the
timer in nf_conn.
