Hi John,
Is there any code that calls scsi_execute() from a code path in which
performance matters?
Eh, I don't know. Does performance matter for the touched ioctls or
probe lun code?
Anyway, this code I mention is just the same as before. It just bugs me
when I see code which accepts a hardcoded value (dma dir, in this case)
and translates into another value, when the translated value could be
just passed.
Thanks,
John
