Subject: [PATCH v2 2/4] selftests/resctrl: Return MBA check result and make it to output message
Date: Wed,  5 Oct 2022 10:39:31 +0900	[thread overview]
Message-ID: <20221005013933.1486054-3-tan.shaopeng@jp.fujitsu.com> (raw)
In-Reply-To: <20221005013933.1486054-1-tan.shaopeng@jp.fujitsu.com>

Since MBA check result is not returned, the MBA test result message
is always output as "ok" regardless of whether the MBA check result is
true or false.

Make output message to be "not ok" if MBA check result is failed.
