Hm. That might be worth changing the API for. Right now, I'm
overloading the return value of kcounter_claim with an errno and a
cookie. Maybe we should go for:
extern int __must_check kcounter_claim(struct kcounter *kc, kcounter_cookie_t *resource);
with the return value being 0 or errno and on success, kcounter_claim
writes a cookie to 'resource'?
