Subject: [PATCH] virtio_blk: decrement index when blockdevice is removed
Date: Tue, 5 Apr 2011 00:49:41 -0400 (EDT)	[thread overview]
Message-ID: <1969774563.659835.1301978981017.JavaMail.root@zmail07.collab.prod.int.phx2.redhat.com> (raw)
In-Reply-To: <1099995365.641718.1301903899721.JavaMail.root@zmail07.collab.prod.int.phx2.redhat.com>

When virtio block device is removed, index does not get decremented. When 
another virtio disk is attached it uses the next device letter to the 
one that is suppose to be available.
