This patch series makes two changes to how KUnit test suites are stored and executed: - The .kunit_test_suites section is now used for tests in modules (in lieu of a module_init funciton), as well as for built-in tests. The module loader will now trigger test execution. This frees up the module_init function for other uses. - Instead of storing an array of arrays of suites, have the kunit_test_suite() and kunit_test_suites() macros append to one global (or per-module) list of test suites. This removes a needless layer of indirection. The upshot of this is that it should now be possible to use the kunit_test_suite() and kunit_test_suites() macros to register test suites even from within modules which otherwise had module_init functions. This was proving to be quite a common issue, resulting in several modules calling into KUnit's private suite execution functions to run their tests (often introducing incompatibilities with the KUnit tooling). This series also fixes the thunderbolt, nitro_enclaves, and sdhci-of-aspeed tests to use kunit_test_suite() now that it works. Huge thanks to Jeremy Kerr, who designed and implemented the module loader changes, and to Daniel Latypov for pushing the simplification of the nested arrays in .kunit_test_suites. I've tested this series both with builtin tests, and with modules on x86_64, but there's always the possibility that there's something subtle and nasty on another architecture, so please test!
