linux-kselftest-kunit-5.15-rc1

Browse Source 
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:
 -- 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.
