What I meant was "when patches are posted to xen-devel I will try to
review as much as possible". There is no patch on xen-devel so I haven't
actually reviewed anything, nor can anyone else who is interested in
getting it work review anything.

What I started last Wednesday was refactoring some QEMU code (only
renaming files and making QEMU build), so that QEMU 9pfs doesn't just
assume it is using virtio transport. I didn't mean I started review
anything.

Further discussion should go to xen-devel. There is definitely a need to
get input from wider community to better coordinate this work.
