Subject: [PATCH 03/27] lockdep tests: Improve testing accuracy
Instead of checking whether the tests produced any output, check the
output itself. This patch avoids that e.g. debug output causes the
message "PASSED!" to be reported for failed tests.
Signed-off-by: Bart Van Assche <bvanassche@....org>
