+From 4d9522764985462741c7bb4af1ab231b9251476b Mon Sep 17 00:00:00 2001
+From: Mike Frysinger <vapier@chromium.org>
+Date: Wed, 10 Jan 2018 00:41:43 -0500
+Subject: [PATCH] dtdiff: change to POSIX shell
+
+This changes from the bash-specific process substitution feature to
+reading with pipes.  It relies on /dev/fd or /proc/self/fd existing.
