[libvirt] [PATCH 0/1] Add support for disk serial number in node device code



This small patch extends the information for storage devices to include their serial number.  This information is useful in figuring out which devices are actually multiple paths to the same backend device, as well as identifying devices uniquely across nodes.  This code will be used by the multipath support that I'm working on, but since it's capable of standing alone, and might be useful for other reasons, I'm submitting it separately.
