Subject: [PATCH v2 nf-next 3/3] netfilter: conntrack: l4 protocol trackers can be const
Date: Tue, 7 Nov 2017 07:20:09 +0100 [thread overview]
Message-ID: <20171107062009.2519-4-fw@strlen.de> (raw)
In-Reply-To: <20171107062009.2519-1-fw@strlen.de>
previous patches removed all writes to these structs so we can
now mark them as const.
Signed-off-by: Florian Westphal <fw@strlen.de>
