From 2382b15bcc39228572ccf1d9a1185dcabb84c833 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Bruno=20Pr=C3=A9mont?= Date: Wed, 29 Apr 2009 20:45:17 +0000 Subject: [PATCH] netconsole: take care of NETDEV_UNREGISTER event MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When netconsole is loaded and a network interface fades away (e.g. on rmmod $interface_driver_module) the rmmod remains stuck and some locks are taken that prevent any additional module loading/unloading as well as interface up/down changes. In addition kernel logs (and console) get flooded at 10s interval with [ 122.464065] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 [ 132.704059] unregister_netdevice: waiting for eth0 to become free. Usage count = 1 This patch lets netconsole take NETDEV_UNREGISTER event into account and release the affected interface if it was in use.
