Subject: mm: vmscan: reclaim highmem zone if buffer_heads is over limit
We have been reclaimed highmem zone if buffer_heads is over limit but
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.
Fixes: 6b4f7799c6a5 ("mm: vmscan: invoke slab shrinkers from shrink_zone()")
