Merge tag 'linux-kselftest-kunit-5.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest
Pull Kunit updates from Shuah Khan:
"This consists of:
- Several config fragment fixes from Anders Roxell to improve test
coverage.
- Improvements to kunit run script to use defconfig as default and
restructure the code for config/build/exec/parse from Vitor Massaru
Iha and David Gow.
- Miscellaneous documentation warn fix"
