Looks like this series is consistently causing a NULL pointer deref in the BPF CI:

  - https://travis-ci.com/github/kernel-patches/bpf/builds/226936809
  - https://travis-ci.com/github/kernel-patches/bpf/builds/226909818

Other runs on top of latest bpf-next are fine though:

  - https://travis-ci.com/github/kernel-patches/bpf/builds/226936786

Please double check your series again and fix.

Thanks,
Daniel
