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@kernel.org/
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!
