bpf: Sync kernel ABI header with tooling header for bpf_common.h
I recently fixed up a lot of commits that forgot to keep the tooling headers in sync. And then I forgot to do the same thing in commit cb5f7334d479 ("bpf: add comments to BPF ld/ldx sizes"). Let correct that before people notice ;-). Lawrence did partly fix/sync this for bpf.h in commit d6d4f60c3a09 ("bpf: add selftest for tcpbpf"). Fixes: cb5f7334d479 ("bpf: add comments to BPF ld/ldx sizes") Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
