From e37791ec1ad785b59022ae211f63a16189bacebf Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 10 Mar 2017 09:46:15 -0800 Subject: [PATCH] mpls: Send route delete notifications when router module is unloaded When the mpls_router module is unloaded, mpls routes are deleted but notifications are not sent to userspace leaving userspace caches out of sync. Add the call to mpls_notify_route in mpls_net_exit as routes are freed. Fixes: 0189197f44160 ("mpls: Basic routing support") Signed-off-by: David Ahern Signed-off-by: David S.
