Ahh, I misread the intention here, and didn't notice that it was doing
it on the stupid SCSI ioctl commands, not the lowlevel SCSI "cmd". The
fact that the changelog talked about sending read/write commands down
to the disk confused me.

But please do use ENOIOCTLCMD directly then, instead of using ENOTTY
and turning it into ENOIOCTLCMD.
