Hi Robert, any news for v10 of this patch?

Robert has been asked to stop work on this, after so many submissions.

He has since been focusing on other projects - I don't think there has been any additional effort put forth to get this upstream.

We (XenClient) maintain a patch queue, and will continue to carry this patch, for now.

Ben
