OK so given the state it's in, and assuming you think it is helpful
to let it mature in tree and not out of tree, I think it's
reasonable to try to do it like tcm_vhost is going to do it:
- send me changes to vhost core ASAP (and keep it minimal, e.g.
  use your own header file to export to userspace)
- for other stuff - put in drivers/staging, and ask Greg to merge
