From e34f4c7050e5471b6d4fb25380713937fc837514 Mon Sep 17 00:00:00 2001 From: Tom Parkin Date: Tue, 19 Mar 2013 06:11:14 +0000 Subject: l2tp: export l2tp_tunnel_closeall l2tp_core internally uses l2tp_tunnel_closeall to close all sessions in a tunnel when a UDP-encapsulation socket is destroyed. We need to do something similar for IP-encapsulation sockets. Export l2tp_tunnel_closeall as a GPL symbol to enable l2tp_ip and l2tp_ip6 to call it from their .destroy handlers.
