Subject: mm/vmscan: push lruvec pointer into putback_inactive_pages()
X-Git-Tag: v3.5-rc1~49^2~88
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=27ac81d85e5cfcc755dd5fa3f04dc883ab5d821b;p=platform%2Fkernel%2Flinux-exynos.git

mm/vmscan: push lruvec pointer into putback_inactive_pages()

As zone_reclaim_stat is now located in the lruvec, we can reach it
directly.
