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"
