The fs/dlm stuff can have even more nodes. Righteo, I guess the few 10s of bytes per struct saved by not tracking children if we know that none can ever exist is the aim here? Coming from an embedded background that makes sense to me. >From a conceptual point of view I still think they would work better amalgamated in the configfs case but really this whole discussion is pretty moot.
