+Subject: [PATCH babeltrace] bindings/python: Allow tests to be run externally
+
+Upstream doesn't officially support running their tests externally. The python
+bindings need some tweaks to work in this configuration.
+
+The patch was created by Michael Jeanson <mjeanson@efficios.com> and is under
+discussion with upstream to see if there is a way to support OE's ue case.
+
+Upstream-Status: Inappropriate [oe specific]
