Don't worry about this one, fix is included in patch I posted last Saturday, and will be rebasing, breaking up and submitting to Linus in a couple(?) of days. Basically, Zach Brown's patch to use nr_swap_pages and total_swap_pages, but in rare case of concurrent swapoff, does need to scan that swap_map (with appropriate locking) to give sensible numbers without strange negatives at that time.
