+From 8edd80d3654843d9441fb5e43dfbf2b3e81f84b5 Mon Sep 17 00:00:00 2001
+From: Mike Frysinger <vapier@gentoo.org>
+Date: Mon, 14 Mar 2016 16:56:40 -0400
+Subject: [PATCH] include sys/sysmacros.h for major() & minor()
+
+Linux C libraries are looking to disentangle sysmacros.h from the
+sys/types.h header to clean up namespace pollution.  Since these
+macros are provided in glibc/etc... today, switch to pulling in
+this header directly.
