This may already be handled?
submit_bh() calls submit_bio() which calls __generic_make_request() and there we do:
if (unlikely(bio_sectors(bio) > q->max_hw_sectors)) { printk("bio too big device %s (%u > %u)\n", bdevname(bio->bi_bdev, b), bio_sectors(bio), q->max_hw_sectors); goto end_io; }
So if we try to push a too large buffer down with submit_bh() we get a failure.
