Subject: Re: [RFC 16/20] selftest: Add Time Namespace test for supported
 clocks

Hi Dmitry,

Thanks for adding tests with the kernel changes.

It would good to elaborate a bit more on the nature of the tests in the
here. Also a few things to consider.

I noticed that this test isn't added to selftests/Makefile as TARGET. If it is
an oversight, please make that change as well. If not, it is fine.

Please make sure if the test can't be run because of unmet dependencies, the test
will exit with KSFT_SKIP as opposed to an error. Dependencies include configuration,
privilege, any other unsupported conditions.

This is a comment applies to all the test patches in this series.

thanks,
-- Shuah
