Subject: [PATCH bpf-next 0/5] switch samples and tests to libbpf perf buffer API

There were few more tests and samples that were using custom perf buffer setup
code from trace_helpers.h. This patch set gets rid of all the usages of those
and removes helpers themselves. Libbpf provides nicer, but equally powerful
set of APIs to work with perf ring buffers, so let's have all the samples use
that and server as a good example.

Andrii Nakryiko (5):
  selftests/bpf: convert test_get_stack_raw_tp to perf_buffer API
  selftests/bpf: switch test_tcpnotify to perf_buffer API
  samples/bpf: convert xdp_sample_pkts_user to perf_buffer API
  samples/bpf: switch trace_output sample to perf_buffer API
  selftests/bpf: remove perf buffer helpers
