From 06689b5d686799ce2c8c9b2955b075433641dc62 Mon Sep 17 00:00:00 2001
From: Rolf Neugebauer <rolf.neugebauer@docker.com>
Date: Tue, 21 Nov 2017 11:22:07 +0000
Subject: [PATCH] tests: Add kernel module tests for all supported kernels

Also add libelf-dev as this is needed for ORC_UNWINDER. While this is only
a feature of 4.14.x we added it to all Dockerfiles to keep things in synch.
