Andrew,
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 :(
Yep. The sooner we kill buffer heads and use submit_bio(), the better :)
