From 8d8fc29d02a33e4bd5f4fa47823c1fd386346093 Mon Sep 17 00:00:00 2001 From: Amerigo Wang Date: Thu, 19 May 2011 21:39:10 +0000 Subject: netpoll: disable netpoll when enslave a device V3: rename NETDEV_ENSLAVE to NETDEV_JOIN Currently we do nothing when we enslave a net device which is running netconsole. Neil pointed out that we may get weird results in such case, so let's disable netpoll on the device being enslaved. I think it is too harsh to prevent the device being ensalved if it is running netconsole. By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole netdev notifier, because netpoll will check if the device is running or not and we don't handle NETDEV_PRE_UP neither. This patch is based on net-next-2.6. Signed-off-by: WANG Cong Cc: Neil Horman Signed-off-by: David S.
