Rafael J. Wysocki d6277db4ab [PATCH] swsusp: rework memory shrinker ... Rework the swsusp's memory shrinker in the following way: - Simplify balance_pgdat() by removing all of the swsusp-related code from it. - Make shrink_all_memory() use shrink_slab() and a new function shrink_all_zones() which calls shrink_active_list() and shrink_inactive_list() directly for each zone in a way that's optimized for suspend. In shrink_all_memory() we try to free exactly as many pages as the caller asks for, preferably in one shot, starting from easier targets.  If slab caches are huge, they are most likely to have enough pages to reclaim.  The inactive lists are next (the zones with more inactive pages go first) etc. Each time shrink_all_memory() attempts to shrink the active and inactive lists for each zone in 5 passes.  In the first pass, only the inactive lists are taken into consideration.  In the next two passes the active lists are also shrunk, but mapped pages are not reclaimed.  In the last two passes the active and inactive lists are shrunk and mapped pages are reclaimed as well. The aim of this is to alter the reclaim logic to choose the best pages to keep on resume and improve the responsiveness of the resumed system. Signed-off-by: Rafael J.
