------------------------------------------------------
Subject: mount options: fix hostfs
From: Miklos Szeredi <mszeredi@xxxxxxx>
Add the "host path" option to /proc/mounts for UML hostfs filesystems.
The mount source (mnt_devname) should really be used for this, but not
easy to change now in a backward compatible way.
