Hello, I've attempted to ping Nirmal directly on the VMD patch, but got no reply so far.
First version of this series was posted on 10/01, yet there hasn't been any feedback from Nirmal. Would it be possible to merge this without Nirmal Ack due to timeout? It's not even a new feature, just a bugfix that allows running with VMD devices when using Xen. Thanks, Roger.
