Re: [PATCH v2 3/3] kunit: Update kunit_print_ok_not_ok function

On Fri, 14 Apr 2023 at 23:28, Michal Wajdeczko michal.wajdeczko@intel.com wrote:

There is no need use opaque test_or_suite pointer and is_test flag as we don't use anything from the suite struct. Always expect test pointer and use NULL as indication that provided results are from the suite so we can treat them differently.

Since results could be from nested tests, like parameterized tests, add explicit level parameter to properly indent output messages and thus allow to reuse this function from other places.

While around, remove small code duplication near skip directive.

From a quick glance, this looks pretty good to me, thanks.

It'll need rebasing on top of the kselftest/kunit[1] tree: there are some conflicts with the debugfs fixes.

I can do that if you'd prefer: I'll need to do so before giving it a more thorough review next week.

Cheers, -- David
