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:
In file included from [...]/libmount/libmount.h:31:0,
