The expectation is that if the notify_failure handler cannot run then there are no scenarios where it needs to run. In other words the expected semantic is that page->index and page->mapping are valid for memory_failure() when the conditions that cause -EOPNOTSUPP in xfs_dax_notify_failure() are present. A fallback to the generic memory_failure() path is expected so do not warn when that happens.
