From 40659392ff90fc9c2861ec18c34ed1bdb54f92ca Mon Sep 17 00:00:00 2001
From: Jes Sorensen <jsorensen@fb.com>
Date: Wed, 30 May 2018 11:56:37 -0400
Subject: [PATCH 14/26] super-intel: Avoid gcc-8.1 complaining about truncating
snprintf()
We know the max size of the volume name, so no need to play the
