Merge tag 'linux-kselftest-kunit-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull kunit updates from Shuah Khan:
 "This kunit update consists of:

   - debugfs support for displaying kunit test suite results.

     This is especially useful for module-loaded tests to allow
     disentangling of test result display from other dmesg events.
     CONFIG_KUNIT_DEBUGFS enables/disables the debugfs support.

   - Several fixes and improvements to kunit framework and tool"

* tag 'linux-kselftest-kunit-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest:
  kunit: tool: add missing test data file content
  kunit: update documentation to describe debugfs representation
  kunit: subtests should be indented 4 spaces according to TAP
  kunit: add log test
  kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display
  Documentation: kunit: Make the KUnit documentation less UML-specific
  Fix linked-list KUnit test when run multiple times
  kunit: kunit_tool: Allow .kunitconfig to disable config items
  kunit: Always print actual pointer values in asserts
  kunit: add --make_options
  kunit: Run all KUnit tests through allyesconfig
  kunit: kunit_parser: make parser more robust
