apart from that we dont like this kind of static stuff, this seems like
nice case for having simple handler like 'struct bpf_objects' carrying
the above data.. what do I miss?

I want to avoid fragmented memory allocation for storing bpf_object pointers. Storing them together into an array can make code simpler. I think I can made
something like 'struct bpf_object *bpf_next_object(obj)' in libbpf so we can
iterate over each loaded bpf objects, then this array and nr_objects can be
hidden.

also params should actually be static right?
