Merge tag 'linux-kselftest-kunit-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull KUnit updates from Shuah Khan: "This consists of several fixes and an important feature to discourage running KUnit tests on production systems. Running tests on a production system could leave the system in a bad state. Summary: - Add a new taint type, TAINT_TEST to signal that a test has been run. This should discourage people from running these tests on production systems, and to make it easier to tell if tests have been run accidentally (by loading the wrong configuration, etc) - Several documentation and tool enhancements and fixes" * tag 'linux-kselftest-kunit-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (29 commits) Documentation: KUnit: Fix example with compilation error Documentation: kunit: Add CLI args for kunit_tool kcsan: test: Add a .kunitconfig to run KCSAN tests kunit: executor: Fix a memory leak on failure in kunit_filter_tests clk: explicitly disable CONFIG_UML_PCI_OVER_VIRTIO in .kunitconfig mmc: sdhci-of-aspeed: test: Use kunit_test_suite() macro nitro_enclaves: test: Use kunit_test_suite() macro thunderbolt: test: Use kunit_test_suite() macro kunit: flatten kunit_suite*** to kunit_suite** in .kunit_test_suites kunit: unify module and builtin suite definitions selftest: Taint kernel when test module loaded module: panic: Taint the kernel when selftest modules load Documentation: kunit: fix example run_kunit func to allow spaces in args Documentation: kunit: Cleanup run_wrapper, fix x-ref kunit: test.h: fix a kernel-doc markup kunit: tool: Enable virtio/PCI by default on UML kunit: tool: make --kunitconfig repeatable, blindly concat kunit: add coverage_uml.config to enable GCOV on UML kunit: tool: refactor internal kconfig handling, allow overriding kunit: tool: introduce --qemu_args ...
