+Subject: [PATCH] core: don't include libmount.h in a header file (#8580)
+
+linux/fs.h sys/mount.h, libmount.h and missing.h all include MS_*
+definitions.
+
+To avoid problems, only one of linux/fs.h, sys/mount.h and libmount.h
+should be included. And missing.h must be included last.
+
+Without this, building systemd may fail with:
+
