[kunit,0/3] kunit: add debugfs representation to show results/run tests

Message

When kunit tests are run on native (i.e. non-UML) environments, the results
of test execution are often intermixed with dmesg output.  This patch
series attempts to solve this by providing a debugfs representation
of the results of the last test run, available as

/sys/kernel/debug/kunit/<testsuite>/results

In addition, we provide a way to re-run the tests and show results via

/sys/kernel/debug/kunit/<testsuite>/run

Alan Maguire (3):
  kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display
  kunit: add "run" debugfs file to run suites, display results
  kunit: update documentation to describe debugfs representation
