mm, page_alloc: remove unnecessary recalculations for dirty zone balancing
File-backed pages that will be immediately written are balanced between zones. This heuristic tries to avoid having a single zone filled with recently dirtied pages but the checks are unnecessarily expensive. Move consider_zone_balanced into the alloc_context instead of checking bitmaps multiple times. The patch also gives the parameter a more meaningful name.
