Should the driver be responsible to catch these kinds of errors
on a passthrough IOCTL? Why not let the device deal with it?

Yeah, I have a drive with accessible LBAs outside the reported
capacity (queue the criticism). I wouldn't use the SCSI
translation layer for that device anyway, so this isn't a NAK.

I'm all for the rest of the series; looks good to me!
