It won't be useful in the kernel unless there are actual consumers, of which Xen could/might be one. Having a use case flesh out problems and get the performance and design architecture examined in detail will be useful to the Linux maintainers - they get something more robust and better designed, although it's certainly not Xen's obligation to provide that, per se. I'm just seeing the possibility of mutual benefit, here. That said, I believe since the patch is in the device-mapper tree for review, there is a good chance it will go into kernel in any case. thanks, Nivedita
