Clone Cinder-Backed Image (Ussuri)

Hi, I have made a cinder-backed image where my cinder is RBD-backed. The backing topology of that image is as follows. glance -> cinder -> RBD. Is it possible to clone that image like RBD-backed images? I think the following bluprint is related but I don't know if it has been implemented yet, at least on Ussuri. https://blueprints.launchpad.net/cinder/+spec/clone-image-in-glance-cinder-b...
