    This would appear to be duplicating the struct scsi_disk media_present
    flag. Moving the media_present flag from scsi_disk to scsi_device may
    make a bit of sense long term ... however, there's also dupication with
    the sr driver and the cdrom layer now (that stores media change at the
    cdrom level), so is there an argument why it's better in scsi_device
    than scsi_disk?
