From 5e8e35fb7e17495032e144f319517dcae38d1b56 Mon Sep 17 00:00:00 2001
From: Jes Sorensen <jsorensen@fb.com>
Date: Thu, 20 Apr 2017 00:19:44 -0400
Subject: [RHEL7.5 PATCH 084/169] maps: Use keyvalue for null terminator to
indicate 'unset' value
This simplifies the code calling map_name() so it no longer has to
manually check for UnSet and convert the value manually.
