Subject: [PATCH v1] selftests/mm: sigbus-wp test requires UFFD_FEATURE_WP_HUGETLBFS_SHMEM
Date: Thu, 21 Mar 2024 23:20:21 +0000 [thread overview]
Message-ID: <20240321232023.2064975-1-edliaw@google.com> (raw)
The sigbus-wp test requires the UFFD_FEATURE_WP_HUGETLBFS_SHMEM flag for
shmem and hugetlb targets. Otherwise it is not backwards compatible
with kernels <5.19 and fails with EINVAL.
