Merge tag 'ktest-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-ktest

Pull ktest updates from Steven Rostedt:

 - Have config-bisect save the good/bad configs at each step.

 - Show log file location even on success

 - Add PRE_TEST_DIE to kill test if the PRE_TEST fails

 - Add a NOT operator for conditionals in config file

 - Add the log output of the last test when emailing on failure.

 - Other minor clean ups and small fixes.
