[PATCH v5 3/5] kselftest: run tests by fixture

Jakub Kicinski
2020-03-18T01:02:45Z

Now that all tests have a fixture object move from a global
list of tests to a list of tests per fixture.

Order of tests may change as we will now group and run test
fixture by fixture, rather than in declaration order.
