From f0c0c115fb81940f4dba0644ac2a8a43b39c83f3 Mon Sep 17 00:00:00 2001 From: Shakeel Butt Date: Mon, 14 Dec 2020 19:07:17 -0800 Subject: mm: memcontrol: account pagetables per node For many workloads, pagetable consumption is significant and it makes sense to expose it in the memory.stat for the memory cgroups. However at the moment, the pagetables are accounted per-zone. Converting them to per-node and using the right interface will correctly account for the memory cgroups as well.
