In commit 7e119cff9d0a ("ocfs2: convert w_pages to w_folios") the chunk page allocations became order 0 folio allocations. If an allocation failed, the folio array entry should be NULL so the error path can skip the entry. In the port it is -ENOMEM and the error path panics trying to free this bad value.
