in this patch series i'm adding a helper for libbpf which would allow it to load map-in-map(BPF_MAP_TYPE_ARRAY_OF_MAPS and BPF_MAP_TYPE_HASH_OF_MAPS). first patch contains new helper + explains proposed workflow second patch contains tests which also could be used as example of usage
v2->v3: - fixing typo in patch description - initializing inner_map_fd to -1 by default v1->v2: - addressing nits - removing const identifier from fd in new helper - starting to check return val for bpf_map_update_elem Nikita V.
