I truly appreciate your time and effort in reviewing my patches and
making the necessary modifications. I've carefully examined the
updated code in the branch you kindly provided:

https://github.com/sean-jc/linux/branches x86/pmu_counter_tests

I completely agree with the changes you made. Please feel free to post
the modified branch as v5 next week. I will add AMD counters related
selftests after this patch set is merged.

Thank you once again for your time and guidance.
