Subject: [PATCH 4.12 14/27] cpuset: Fix incorrect memory_pressure control file mapping
Date: Tue, 5 Sep 2017 09:11:30 +0200 [thread overview]
Message-ID: <20170905070923.799999636@linuxfoundation.org> (raw)
In-Reply-To: <20170905070923.265950493@linuxfoundation.org>
4.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Waiman Long <longman@redhat.com>
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.
