This is the first time I've looked at all at any of the vfio code, but this is still looking good to me. Thanks for taking this on and exposing the vfio code to me. I hope more devices will be able to take advantage of the quirk and get their VPD issues resolved. I did run this on a host with a device with VPD assigned to a guest and did not see any trouble when accessing it concurrently from both the guest and the host on the same and different functions. I don't think my particular environment is ideal to fully reproduce the problem (no writable VPD area), but my initial testing looks good.
