Merge tag 'linux-kselftest-kunit-5.17-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 enhancements. A few highlights:
- Option --kconfig_add option allows easily tweaking kunitconfigs
- make build subcommand can reconfigure if needed
- doesn't error on tests without test plans
- doesn't crash if no parameters are generated
- defaults --jobs to # of cups
- reports test parameter results as (K)TAP subtests"
