Code Issues Proposed changes

Allow LVM to scan all loop devices 

This patch allows all loop devices to be scanned by LVM and this
fixes a bug that occurs after a reboot in AIOs when the loop device
numbering is shuffled. For example, the cinder loopback may be
mounted from /dev/loop4 when the AIO is first built, but it might
come up as /dev/loop0 when the AIO reboots.
