There is another approach to providing LIO support that doesn't result
in AGPL code used directly by Cinder code.  That is to use targetd
instead of rtslib directly.  This was actually the original proposal:

    https://github.com/agrover/targetd

It eventually morphed into initial support using rtslib directly.

It sounds like revisiting this for Havana would be a very good idea.
