Subject: [PATCH 4/9] lkdtm/bugs: XFAIL UNALIGNED_LOAD_STORE_WRITE
Date: Wed, 23 Jun 2021 13:39:31 -0700	[thread overview]
Message-ID: <20210623203936.3151093-5-keescook@chromium.org> (raw)
In-Reply-To: <20210623203936.3151093-1-keescook@chromium.org>

When built under CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS, this test is
expected to fail (i.e. not trip an exception).

Fixes: 46d1a0f03d66 ("selftests/lkdtm: Add tests for LKDTM targets")
Cc: stable@vger.kernel.org
