------------------------------------------------------ From: Edward Liaw edliaw@google.com Subject: selftests/mm: sigbus-wp test requires UFFD_FEATURE_WP_HUGETLBFS_SHMEM Date: Thu, 21 Mar 2024 23:20:21 +0000

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.
