Back in the day when I wrote MSH: (a MSDOS filesystem for the Amiga), I
think I did that. (Locks on) Directories refer to (Locks on) their
parents, so therefore they contribute to their refcount. Open files own
a Lock too, which also refers to its parent directory (Lock), and which
therefore also contributes to its refcount.

It seems that an AmigaOS Lock is comparable with a vnode.
