Names are not unique and IIUC debugfs is not namespaced.
How much naming the objects in a "user readable" fashion actually
matter? It'd be less churn to create some kind of "object class"
with a directory level named after what's already passed to
ref_tracker_dir_init() and then id the objects by the pointer value 
as sub-dirs of that?
