From mboxrd@z Thu Jan 1 00:00:00 1970 From: Waiman Long Subject: [PATCH] cpuset: Fix incorrect memory_pressure control file mapping Date: Thu, 24 Aug 2017 12:04:29 -0400 Message-ID: <1503590669-16601-1-git-send-email-longman@redhat.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org List-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Tejun Heo , Li Zefan , Johannes Weiner Cc: cgroups@vger.kernel.org, linux-kernel@vger.kernel.org, Waiman Long 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.
