I mistakenly thought that the md raid stuff was already moved over, since the patch to move the transport was suggested. If it isn't and SCSI is still the sole user of that code, then by all means keep it there. Once patches for md or eg cciss or other block raid controllers are supplied, then it'll make sense to move the transport class. IOW, I completely agree with you James and thought we were further ahead than we really are :-) -- Jens Axboe
