If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 1c08c22c874ac88799cab1f78c40f46110274915 Mon Sep 17 00:00:00 2001 From: Waiman Long <longman@xxxxxxxxxx> Date: Thu, 24 Aug 2017 12:04:29 -0400 Subject: cpuset: Fix incorrect memory_pressure control file mapping From: Waiman Long <longman@xxxxxxxxxx> commit 1c08c22c874ac88799cab1f78c40f46110274915 upstream. The memory_pressure control file was incorrectly set up without a private value (0, by default). As a result, this control file was treated like memory_migrate on read. By adding back the FILE_MEMORY_PRESSURE private value, the correct memory pressure value will be returned.
