Subject: [PATCH] virtio: decrement dev_index when device is unregistered
Date: Tue, 5 Apr 2011 00:49:26 -0400 (EDT) [thread overview]
Message-ID: <66015840.659833.1301978966706.JavaMail.root@zmail07.collab.prod.int.phx2.redhat.com> (raw)
In-Reply-To: <1457566934.641329.1301903526622.JavaMail.root@zmail07.collab.prod.int.phx2.redhat.com>
When virtio device is removed, dev_index does not get decremented.
The next device hotplug event results in consuming the next pci to
the one that is suppose to be available.
