Thanks for this and the other patch that Linus already merged, I'll

breakage, but I had naively thought it only affected -mm additions.

Oh, and Linus don't apply this one if you beat me to submitting a pull
request, the bi_end_io() changes aren't complete (they need bi_size
check updated as well).
