-Subject: [mdadm PATCH] Add missing include file sys/sysmacros.h
+From 452dc4d13a012cdcb05088c0dbc699959c4d6c73 Mon Sep 17 00:00:00 2001
+From: Baruch Siach <baruch@tkos.co.il>
+Date: Tue, 6 Aug 2019 16:05:23 +0300
+Subject: mdadm.h: include sysmacros.h unconditionally
 
-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.
+musl libc now also requires sys/sysmacros.h for the major/minor macros.
+All supported libc implementations carry sys/sysmacros.h, including
+diet-libc, klibc, and uclibc-ng.
