I have some patches pending as part of my next DIF/DIX update that makes
some of these things more palatable at the block/SCSI level. Akinobu
voiced interest in finishing the scsi_debug work on top of my code.
Yes. I'm interested in that work. Before I start working on it, I would
like to fix the problems which I found recently with virtual_gb option in
scsi_debug. Because the change is not small and may touch the DIX/DIF
support code, too.
So Martin and Douglas, can I have your ACKs on this patch series for now?
Done.
Just doing some debugging using scsi_debug and noticed
that 'blockdev --rereadpt /dev/sdb' causes a SCSI
REPORT SUPPORTED OPERATION CODES command to be issued.
Perhaps we could add that one (and ... SUPPORTED TMFs) to
scsi_debug's code.
I was also testing setting the SWP bit in the Control
mode page and that works, even though that field is
marked as 'changeable=n'. Since scsi_debug allows all
fields in that page to be changed, perhaps they could
all be marked as changeable.
