Cover letter [patch 0/2] vmscan: one cleanup, one bugfix
Hi Andrew,
the first patch is from KOSAKI Motohiro, it moves the suspend-to-disk memory shrinking functions to use sc.nr_reclaimed all over instead of maintaining an extra local variable.
The second patch is a bugfix for shrink_all_memory() which currently does reclaim more than requested because of setting swap_cluster_max once to our overall reclaim goal but failing to decrease it while we go and reclaim is making progress. Added Nigel Cunningham to Cc because ISTR he complained about exactly this behaviour. Well, this patch seems to fix it, I even added some shiny numbers coming from real tests!
