4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Minchan Kim <minchan@kernel.org>
commit 7bf52fb891b64b8d61caf0b82060adb9db761aec upstream.
We have been reclaimed highmem zone if buffer_heads is over limit but commit 6b4f7799c6a5 ("mm: vmscan: invoke slab shrinkers from shrink_zone()") changed the behavior so it doesn't reclaim highmem zone although buffer_heads is over the limit. This patch restores the logic.
