[PATCH bpf-next v3 00/13] bpf: implement bpf iterator for map elements

Bpf iterator has been implemented for task, task_file, bpf_map, ipv6_route, netlink, tcp and udp so far. For map elements, there are two ways to traverse all elements from user space: 1. using BPF_MAP_GET_NEXT_KEY bpf subcommand to get elements one by one. 2. using BPF_MAP_LOOKUP_BATCH bp
