Subject: [PATCH v11 5/5] kasan: don't run tests in async mode
Date: Sat, 30 Jan 2021 16:52:25 +0000 [thread overview]
Message-ID: <20210130165225.54047-6-vincenzo.frascino@arm.com> (raw)
In-Reply-To: <20210130165225.54047-1-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.
