Subject: [PATCH v5 7/7] locking-selftests: handle unexpected failures more strictly
Date: Thu, 20 Jun 2013 13:31:51 +0200	[thread overview]
Message-ID: <20130620113151.4001.77963.stgit@patser> (raw)
In-Reply-To: <20130620112811.4001.86934.stgit@patser>

When CONFIG_PROVE_LOCKING is not enabled, more tests are expected to
pass unexpectedly, but there no tests that should start to fail that
pass with CONFIG_PROVE_LOCKING enabled.
