[PATCH v11 5/5] kasan: don't run tests in async mode

From: Vincenzo Frascino
Date: Sat Jan 30 2021 - 11:54:25 EST


From: Andrey Konovalov <andreyknvl@xxxxxxxxxx>

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.
