    In samples/bpf/ there's sockex3* that would exercise it, or
    alternatively in iproute2 repo under examples/bpf/ there's
    bpf_cyclic.c and bpf_tailcall.c as a prog.

    Hm, generally, we should really add a test case also to BPF
    selftest suite to facilitate that. I'll likely do that for
    the next batch of BPF patches.
