Hi Dongjiu -- it looks like this patch set is extending the API KVM provides to userspace, but it doesn't update the documentation in Documentation/virtual/kvm/api.txt. I appreciate the API is still somewhat under discussion, but if you can include the docs updates it's helpful to me for reviewing whether the API makes sense from the userspace consumer end of it. thanks -- PMM
