This whole patch looks like a layering violation. Why not just update
the SAT layer to translate the MODE SENSE correctly?
Would plz you explain more ? I didn't clearly understand your point yet.
The ATA layer does translation for SCSI commands. Just translate the
mode sense correctly to use IDENTIFY word 85. It's a smaller patch and
no need for any changes in SCSI.
Correct.
Actually, looking at it, it seems to be correct ... why is it not
working for you?
Indeed -- the patch attempts to address a problem that the libata-scsi
translation module already handles.
I would look at why the device is not properly reporting that already.
If necessary, we would update libata not SCSI.
