page-allocator: add inactive ratio calculation function of each zone
Factor the per-zone arithemetic inside setup_per_zone_inactive_ratio()'s loop into a a separate function, calculate_zone_inactive_ratio(). This function will be used in a later patch [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Minchan Kim <minchan.kim@gmail.com> Reviewed-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: Rik van Riel <riel@redhat.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
