There is no functionality change for this patch.
Struct bpf_iter_reg is used to register a bpf_iter target,
which includes information for both prog_load, link_create
and seq_file creation.
This patch puts fields related seq_file creation into
a different structure. This will be useful for map
elements iterator where one iterator covers different
map types and different map types may have different
seq_ops, init/fini private_data function and
private_data size.

bpf: Add bpf_prog iterator2020-07-26T03:16:32ZAlexei Starovoitovast@kernel.org2020-07-02T01:10:18Zurn:sha1:a228a64fc1e4428e2b96dc68e9ad3c447095c9e7
It's mostly a copy paste of commit 6086d29def80 ("bpf: Add bpf_map iterator")
that is use to implement bpf_seq_file opreations to traverse all bpf programs.
v1->v2: Tweak to use build time btf_id
