Subject: [PATCH net-next 3/8] UDP: add struct net argument to udp_hashfn
Date: Mon, 16 Jun 2008 13:41:33 +0400 [thread overview]
Message-ID: <4856354D.9040104@openvz.org> (raw)
In-Reply-To: <485633E4.10900@openvz.org>
Every caller already has this one. The new argument is currently
unused, but this will be fixed shortly.
