The next patch adds filemap_alloc_folio() which uses these. That then gets used in "mm/filemap: Add filemap_get_folio", which is the patch after that. Now that I look at this patch again, I wonder if this shouldn't be folio_alloc(), __folio_alloc() and __folio_alloc_node. And even though I have no users yet, completing the set with folio_alloc_node() might be a good idea.
