Subject: [bpf-next 0/3] samples/bpf: Remove obsolete tracing-related tests

The BPF tracing infrastructure has undergone significant evolution,
leading to the introduction of more robust and efficient APIs.
However, some of the existing tests in the samples/bpf directory have
not kept pace with these developments. These outdated tests not only
create confusion among users but also increase maintenance overhead.

For starter, this patchset focuses on cleaning up outdated 'tracing'
related tests within the BPF testing framework. The goal is to
modernize and streamline selftests by removing obsolete tests and
migrating necessaries to more appropriate locations.

Daniel T. Lee (3):
  selftests/bpf: migrate tracepoint overhead test to prog_tests
  selftests/bpf: add rename tracepoint bench test
  samples/bpf: remove obsolete tracing related tests
