For 6-byte r/w commands, transfer length 0 means 256 blocks of data, not 0 block. But some drivers consider transfer length 0 as 0 block. Fortunately, the scsi disk driver sets up 10-byte r/w commands for 256 blocks of data instead of 6-byte r/w commands. So this could be an issue when SCSI commands are issued by SG_IO ioctl.
