    mnt: Improve the umount_tree flags · 6b1353cb

    - Remove the unneeded declaration from pnode.h
    - Mark umount_tree static as it has no callers outside of namespace.c
    - Define an enumeration of umount_tree's flags.
    - Pass umount_tree's flags in by name
    
    This removes the magic numbers 0, 1 and 2 making the code a little
    clearer and makes it possible for there to be lazy unmounts that don't
    propagate.  Which is what __detach_mounts actually wants for example.
