Thanks for respining these patches, but I think we really need to see a
driver using this in order to get an idea of how it will be used.

Also, the Xen and KVM people need to agree on the userspace interface
here, perhaps also getting some libvirt involvement as well, as they are
going to be the ones having to use this all the time.

thanks,
