Subject: [PATCH 05/52] netfilter: conntrack: timeouts can be const
Date: Mon, 8 Jan 2018 21:19:13 +0100 [thread overview]
Message-ID: <20180108202000.12989-6-pablo@netfilter.org> (raw)
In-Reply-To: <20180108202000.12989-1-pablo@netfilter.org>
From: Florian Westphal <fw@strlen.de>
Nowadays this is just the default template that is used when setting up
the net namespace, so nothing writes to these locations.
