Merge tag 'linux-kselftest-kunit-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull KUnit updates from Shuah Khan: "This KUnit update for Linux 5.15-rc1 adds new features and tests: Tool: - support for '--kernel_args' to allow setting module params - support for '--raw_output' option to show just the kunit output during make Tests: - new KUnit tests for checksums and timestamps - Print test statistics on failure - Integrates UBSAN into the KUnit testing framework. It fails KUnit tests whenever it reports undefined behavior" * tag 'linux-kselftest-kunit-5.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: kunit: Print test statistics on failure kunit: tool: make --raw_output support only showing kunit output kunit: tool: add --kernel_args to allow setting module params kunit: ubsan integration fat: Add KUnit tests for checksums and timestamps
