492 | * the sg driver have become available via the SG_IO ioctl which is available | |
493 | * on all SCSI devices (on SCSI tape devices from lk 2.6.6). | |
494 | * So the strategy below is to find out if the SG_IO ioctl is available and | |
495 | * if so use it; failing that use the older SCSI_IOCTL_SEND_COMMAND ioctl. | |
