Merge tag 'linux-kselftest-kunit-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull KUnit updates from Shuah Khan: "Several fixes, cleanups, and enhancements to tests and framework: - introduce _NULL and _NOT_NULL macros to pointer error checks - rework kunit_resource allocation policy to fix memory leaks when caller doesn't specify free() function to be used when allocating memory using kunit_add_resource() and kunit_alloc_resource() funcs. - add ability to specify suite-level init and exit functions" * tag 'linux-kselftest-kunit-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: (41 commits) kunit: tool: Use qemu-system-i386 for i386 runs kunit: fix executor OOM error handling logic on non-UML kunit: tool: update riscv QEMU config with new serial dependency kcsan: test: use new suite_{init,exit} support kunit: tool: Add list of all valid test configs on UML kunit: take `kunit_assert` as `const` kunit: tool: misc cleanups kunit: tool: minor cosmetic cleanups in kunit_parser.py kunit: tool: make parser stop overwriting status of suites w/ no_tests kunit: tool: remove dead parse_crash_in_log() logic kunit: tool: print clearer error message when there's no TAP output kunit: tool: stop using a shell to run kernel under QEMU kunit: tool: update test counts summary line format kunit: bail out of test filtering logic quicker if OOM lib/Kconfig.debug: change KUnit tests to default to KUNIT_ALL_TESTS kunit: Rework kunit_resource allocation policy kunit: fix debugfs code to use enum kunit_status, not bool kfence: test: use new suite_{init/exit} support, add .kunitconfig kunit: add ability to specify suite-level init and exit functions kunit: rename print_subtest_{start,end} for clarity (s/subtest/suite) ...
