As said in other reply I do not think this is a good fit for this
specific case as it is all or nothing approach. Soon enough we discover
that "no effort to reclaim/compact" hurts other usecases. So I do not
think we need a dedicated flag for this specific case. We need a way to
tell kswapd/kcompactd how much to try instead.
