Subjectperf: fuzzer leads to trace_kprobe: Could not insert message flood
Author: Song Liu <songliubraving@fb.com>

When running the perf_fuzzer on a current git checkout my logs are flooded
with messages such as this:
[71487.869077] trace_kprobe: Could not insert probe at unknown+0: -22
[71488.174479] trace_kprobe: Could not insert probe at unknown+0: -22

Presumably this is due to the introduction of the perf_kprobe PMU in
commit e12f03d7031a977356e3d7b75a68c2185ff8d155

Is there a way to get this error disabled, or else rate-limited?

Vince
