Shouldn't this match some perf_pmu_test_event entry with same
matching_pmu member? But is perf_pmu_test_event.matching_pmu member ever
used for any checking???

I need to double check because I was testing against 6.3-rc2.

That 6.3-rc2, was for the the kernel? Or baseline for this series? See
see maintainers for git/branch to base perf tool dev on.

I have now developed based on the latest perf tool, but I'm still confused.
"matching_pmu" does not seem to have any effect. No matter what value matching_pmu
is, it will not affect the final test result.
