With node-lru, if there are enough reclaimable pages in highmem
but nothing in lowmem, VM can try to shrink inactive list although
the requested zone is lowmem.
The problem is direct reclaimer scans inactive list is fulled with
highmem pages to find a victim page at a reqested zone or lower zones
With node-lru, if there are enough reclaimable pages in highmem
but nothing in lowmem, VM can try to shrink inactive list although
the requested zone is lowmem.
