Yes. And no.
The patchset is meant to be as a drop-in replacement, ie with _no_ user
visible changes.
So I retained the original output.
Also, the above number is identical to the sysfs representation, where
the user will find a device like
/sys/class/scsi_device/X:Y:Z:L
with each X, Y, Z, and L being a decimal number.
_If_ we were to change that we would have to do it consistently for all
instances, plus the sysfs layout.
But I guess we need to have a discussion about this, as I think not
everybody agrees with that assessment.
Would be a nice topic for LSF, though.
Cheers,
Hannes
