Subject: [PATCH] include/linux/memcontrol.h: fix comments based on per-node
 memcg

References: bnc#1155780 (VM/FS functional and performance backports)
Patch-mainline: v5.5-rc1
Git-commit: 242c37b459ce9ea1be53b75bdb76a7d9268a0791

These comments should be updated as memcg limit enforcement has been
moved from zones to nodes.
