Am I right in saying that first_sect & last_sect in blkif_request_segment are the relative sector numbers in the transfer? So if I wanted to transfer 9 sectors starting at 100, the resultant contents of the request would look like: req->sector_number = 100 req->seg[0].first_sect = 0 req->seg[0].last_sect = 3 req->seg[1].first_sect = 4 req->seg[1].last_sect = 7 req->seg[2].first_sect = 8 req->seg[2].last_sect = 8 ?
