[PATCH bpf-next 0/2] compute bpf_skc_to_*() helper socket btf ids at build time

[Yonghong Song <yhs@fb.com>]

Commit af7ec1383361 ("bpf: Add bpf_skc_to_tcp6_sock() helper")
computed btf ids for a list of sockets at runtime when vmlinux_btf
is available. Commit 5a2798ab32ba
("bpf: Add BTF_ID_LIST/BTF_ID/BTF_ID_UNUSED macros") added support
to calculate btf_ids during linux build time. Patch #2
replaced runtime mechanism with new build-time btf_id computation
mechanism. Patch #1 also fixed a minor issue to use "static" instead
of "extern" for variable declaration to conform to actual
variable scope.

Yonghong Song (2):
  bpf: change var type of BTF_ID_LIST to static
  bpf: compute bpf_skc_to_*() helper socket btf ids at build time
