Subject: [PATCH net-next 14/16] l2tp: remove redundant sk_user_data check when creating tunnels
Date: Fri,  9 Feb 2018 15:00:30 +0000	[thread overview]
Message-ID: <1518188432-9245-15-git-send-email-jchapman@katalix.com> (raw)
In-Reply-To: <1518188432-9245-1-git-send-email-jchapman@katalix.com>

l2tp_tunnel_create now checks sk_user_data so this check is redundant
