Subject: [PATCH v6 23/23] selftests/uffd: Enable uffd-wp for shmem/hugetlbfs
Date: Mon, 15 Nov 2021 16:04:06 +0800 [thread overview]
Message-ID: <20211115080406.75377-1-peterx@redhat.com> (raw)
In-Reply-To: <20211115075522.73795-1-peterx@redhat.com>
After we added support for shmem and hugetlbfs, we can turn uffd-wp test on
always now.
