From a use case perspective, I'd like to be able to point to a pv (or
perhaps a vg), and say 'speed up that pv/vg with XG of cache', so hopefully
that will be supported by lvm. My tentative layering for testing dm-cache
prior to lvm support was going to be <raw disk><dm-cache><pv>, ie, the pv
was going to be created on the cached device...
