Re: [PATCH bpf-next v4 5/5] selftests: bpf: test writable buffers in raw tps

This tests that:

• a BPF_PROG_TYPE_RAW_TRACEPOINT_WRITABLE cannot be attached if it uses either:
  • a variable offset to the tracepoint buffer, or
  • an offset beyond the size of the tracepoint buffer
• a tracer can modify the buffer provided when attached to a writable tracepoint in bpf_prog_test_run

BTW, your patches have some conflicts with latest bpf-next, you may want to rebase and resubmit.
