With this patch, the SCSI layer will be able to correctly send WRITE_SAME_16 to the Hyper-V host. It will not send WRITE_SAME_10: it has been disabled in the driver template. Do you want me to send another patch with these details?

This version is used in all current Hyper-V hosts: Windows 2008 R2, 2012 and 2012 R2. However it may change in future Windows releases.
