From 3d04c92403d377918c9a3bddab6ee103f0db25dd Mon Sep 17 00:00:00 2001 From: Casey Schaufler Date: Wed, 12 Aug 2015 11:56:02 -0700 Subject: [PATCH] Smack - Fix build error with bringup unconfigured The changes for mounting binary filesystems was allied improperly, with the list of tokens being in an ifdef that it shouldn't have been.
