+From 1ee119c8026dff34a4d8c4269c05d3d4e0c25aa6 Mon Sep 17 00:00:00 2001
+From: Hauke Mehrtens <hauke@hauke-m.de>
+Date: Sat, 3 Aug 2019 11:03:40 +0200
+Subject: [mdadm PATCH] Add missing include file sys/sysmacros.h
+
+This include file is needed for makedev(), major() and minor() which are
+used in these functions. In musl 1.1.23 sys/sysmacros.h is not included
+indirectly any more and mdadm fails to compile.
+
