[PATCH perf/core 0/5] perf tools: Fix prologue generation

[Jiri Olsa <jolsa@kernel.org>]

hi,
sending change we discussed some time ago [1] to get rid of
some deprecated functions we use in perf prologue code.

Despite the gloomy discussion I think the final code does
not look that bad ;-)

This patchset removes following libbpf functions from perf:
  bpf_program__set_prep
  bpf_program__nth_fd
  struct bpf_prog_prep_result

Also available in:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/depre

thanks,
jirka
