STATUS_SUCCESS The properties were successfully updated. The driver can start using the allocation with its new property immediately. PagingFenceValue is invalid, though the driver shouldn't wait on it.
STATUS_PENDING The request has successfully been queued to VidMm and is being processed. The driver must synchronize against the returned PagingFenceValue before using the allocation with its new property. Note that if the driver request is invalid it may still fail at a later point, in which case the device will be put in error.
