Also it should CC the perf tools reviewers and maintainers:

For reviewers, the series of patches can be accessed via the
linux-perf-users mail archive at:

https://lore.kernel.org/linux-perf-users/ZbpPa1ZjoOdGw9Yd@xxxxxxxxxx/

There are many, many tests in Michael's test suite, its super great that
this work is being done so that people using 'perf test' will have a far
greater tool testing coverage,

Again, thanks a lot!
