I looked at this few days ago. I am not sure how we end up having multiple pages (especially, why we end up having buffers with bh_size > pagesize) ? Do you know why ? Easiest fix would be to fix submit_bh() to deal with multiple vecs - which is vetoed by Jens and I agree with him :(
Thanks, Badari
