Oh, really? Sorry, Jason. I didn't know that. Then why's chio.c in
dev/scsi/scsipi? :-)

If that's the case, why don't you then also use the SJI ioctl set,
which Legato and about 6 other companies defined several years back
as the 'standard' ioctls for changer devices (irrespective of the
control path)?

Sorry for misspeaking..
