From b103f358d9f6f58658f1a6dc08912ab921dd86f1 Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Thu, 16 May 2013 23:26:11 +0000 Subject: [PATCH] xen-netback: enable user to unload netback module MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This patch enables user to unload netback module, which is useful when user wants to upgrade to a newer netback module without rebooting the host. Netfront cannot handle netback removal event. As we cannot fix all possible frontends we add module get / put along with vif get / put to avoid mis-unloading of netback. To unload netback module, user needs to shutdown all VMs or migrate them to another host or unplug all vifs before hand. Signed-off-by: Wei Liu Acked-by: Ian Campbell ¬ Signed-off-by: David S.
