Subject: [PATCH v13 7/7] kasan: don't run tests in async mode
Date: Thu, 11 Feb 2021 15:33:53 +0000 [thread overview]
Message-ID: <20210211153353.29094-8-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20210211153353.29094-1-vincenzo.frascino@arm.com>
From: Andrey Konovalov <andreyknvl@google.com>
Asynchronous KASAN mode doesn't guarantee that a tag fault will be
detected immediately and causes tests to fail. Forbid running them
in asynchronous mode.
