The patches are far less scary than I feared they would be and they are
harmless on any platform which doesn't advertise pscsi-0.2 in the device
tree.

I think we currently don't support any pscsi-0.2 aware platforms so
there is no possibility of regressing those, but I fully expect such
systems to become available in the lifetime of 4.5. Testing wise we know
that you have tested on at least one real system, and it's all pretty
simple in any case.

I think we should consider applying for 4.5.

Konrad? What are your thoughts?

Ian.
