Sorry, also forgot to do the __diag() dance described in [0]. I'll
include that fix in v2.
[0]: https://docs.kernel.org/bpf/kfuncs.html#creating-a-wrapper-kfunc
This is also reminding me to send out the v2 for [1]. I'll do that
after I take care of another few small things I've been putting off.

Thanks,
