All you need is

struct wombat_controller
{
        struct user_beancounter counter;
        void (*wombat_pest_control)(struct wombat *w);
        atomic_t wombat_population;
        int (*wombat_destructor)(struct wombat *w);
};

and just embed the counter in whatever you are controlling. The point of
the beancounters themselves is to be *SIMPLE*. It's unfortunate that
some folk seem obsessed with extending them for a million theoretical
projects rather than getting them in and working and then extending them
for real projects. Please lets not have another EVMS.
