From e92036a6516d07f61d4c214970a35ff05b919c25 Mon Sep 17 00:00:00 2001 From: "RongQing.Li" Date: Wed, 23 Nov 2011 23:10:52 +0000 Subject: [PATCH] ipv4: remove useless codes in ipmr_device_event() Commit 7dc00c82 added a 'notify' parameter for vif_delete() to distinguish whether to unregister the device. When notify=1 means we does not need to unregister the device, so calling unregister_netdevice_many is useless. Signed-off-by: RongQing.Li Signed-off-by: David S.
