Good to see this suite added to Kselftest. Thanks for
being thorough and including .gitignore.

Are there any destructive and/or longer time tests
in this suite. If so could you please make them
optional to run. Please see selftests/timers as an
example for excluding.

More comments on individual patches to follow.

thanks,
