[PATCH 2/8] Drivers: scsi: storvsc: Filter commands based on the storage protocol version

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Going forward it is possible that some of the commands that are not currently
implemented will be implemented on future Windows hosts. Make command filtering
depend on the host version.
