Subject: [PATCHv3 0/2] perf/bpf: Replace deprecated code

hi,
the original patchset [1] removed the whole perf functionality
with the hope nobody's using that. But it turned out there's
actually bpf script using prologue functionality, so there
might be users of this.

v3 changes:
  - sending priv related changes, because they can be already
    merged, the rest will need more discussion and work

  - this version gets rid of and adds workaround (and keeps the
    current functionality) for following deprecated libbpf functions:

      bpf_program__set_priv
      bpf_program__priv
      bpf_map__set_priv
      bpf_map__priv

    Basically it implements workarounds suggested by Andrii in [2].

Also available in here:

thanks,
jirka
