4.4-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.
