Note: when compiling using current clang 'main' (make test_progs) this reports the following errors:

In file included from tools/testing/selftests/bpf/prog_tests/arena_list.c:9:
./bpf_arena_list.h:28:59: error: omitting the parameter name in a function
                                 definition is a C23 extension [-Werror,-Wc23-extensions]
   28 | static inline void *bpf_iter_num_new(struct bpf_iter_num *, int, int) { return NULL; }
   ...

So I had to give parameter names for the above functions.
