I just walked through the patch set again and did not notice anything
else. There's still the area of channel path handling, but I don't see
why it shouldn't be able to fit into the infrastructure you introduce
here. (I'd expect most of the interesting stuff there to be handled in
user space anyway.)

You should update MAINTAINERS, though. I'm not sure the s390 cio folks
are prepared to handle vfio-ccw :) (although I think you should cc:
them on the patches exporting cio interfaces.) It's probably best to
take vfio-ccw through the kvm-s390 tree.
