In __blkdev_issue_rw():
> + bio = blk_next_bio(bio, nr_pages, gfp_mask);
Doesn't this already submits the bio even before the pages are added?
> + error = __blkdev_issue_rw(b, buf, sector, nr_sects, op, opf, mask, &bio);
> + if (!error && bio) {

And then the bio is submitted again in blkdev_issue_rw()...
Or do I understand it wrong?
