The reuseport_bpf_numa test case fails there's no numa support. The test shouldn't fail if there's no support it should be skipped with a pass.

I don't know about this.
The test did not pass. So it should not be "skipped with a pass".
You are right that "skipped with pass" is ambiguous. Don't we wish we could have done that in college :)
We were unable to run it at all, which means we don't know if it would pass or fail. This means there is a third state besides pass or fail which we must acknowledge and implement.
Several tests and test scripts treated test that can't be run as errors which is also ambiguous. Test user community requested that they would like Skips to be treated as pass. I think the reasoning is that on ARM systems, several tests get skipped - NUMA happens to be one and there are others. Also the configs. Not all config options might be enabled and tests need to be skipped.
This seems to causing problems for test result analysis.
So I made a call to say - okay let's treat Skip as pass to make it easier for analysis. Some test authors are okay with treating skip as pass. Some test authors don't like doing so. So we are currently in an inconsistent state. Maybe networking tests are the only ones that don't treat skip as pass at the moment. In any case, dependency checks are made from test shell scripts mainly and in some cases from test programs such as bpf_numa and when dependency isn't met, some tests treat it as an error and sone as skip-pass.
Lots of test scripts check for !pass and call it fail. So changing skip as a distinct state requires some work in several tests. Not impossible, just effort.
Kselftest infrastructure on the other hand maintains skip count and for tests skipped, also prints a distinct message for it. Originally skip was treated by the framework as distinct state implying that the test can't be run which makes more sense. Based on the request as stated above, I made a change to map KSFT_SKIP to KSFT_PASS. Several tests use the infrastructure.
That said, I am open to adding a distinct state for skipped because can't be run.
