Subject: [PATCH 21/25] netfilter: nf_conntrack: add nf_ct_timeout_lookup
Date: Tue,  4 Sep 2012 01:54:08 +0200	[thread overview]
Message-ID: <1346716452-3080-22-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1346716452-3080-1-git-send-email-pablo@netfilter.org>

From: Pablo Neira Ayuso <pablo@netfilter.org>

This patch adds the new nf_ct_timeout_lookup function to encapsulate
the timeout policy attachment that is called in the nf_conntrack_in
path.
