Merge tag 'linux-kselftest-kunit-next-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull KUnit updates from Shuah Khan:
 "Several enhancements, fixes, clean-ups, documentation updates,
  improvements to logging and KTAP compliance of KUnit test output:

   - log numbers in decimal and hex

   - parse KTAP compliant test output

   - allow conditionally exposing static symbols to tests when KUNIT is
     enabled

   - make static symbols visible during kunit testing

   - clean-ups to remove unused structure definition"
