[for-next][PATCH 3/8] ktest.pl: Define PRE_TEST_DIE to kill the test if the PRE_TEST fails

From: Steven Rostedt
Date: Wed Jul 01 2020 - 19:18:22 EST


From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>

Currently, if a PRE_TEST is defined and ran, but fails, there's nothing
currently available to make the test fail too. Add a PRE_TEST_DIE option that
when set, if a PRE_TEST is defined and fails, the test will die too.
