+From: "Brad T. Peters" <brad.t.peters@intel.com>
+Date: Thu, 7 Jan 2016 14:37:17 -0800
+Subject: [PATCH] swupd-client: Add existence check to staging target
+
+Patch adds an stat() check to ensure that:
+1. target path for a staged file exists, and
+2. target path is indeed a directory
+
+Follow-on patch will add correct corrective behavior once
+verify_fix_path() is implemented
+
+Upstream-Status: Accepted
+
