Just want to raise a voice of support for this one. Thanks to Glauber's efforts, we might not need another memory pressure interface for CONFIG_MEMCG=n case, since we might have CONFIG_MEMCG=y that will be super cheap when used with just a root memcg w/o children, and still usable for mem pressure. So this particular scenario is actually in demand[1]. Thanks!
