- * fscache_set_page_dirty - Mark page dirty and pin a cache object for writeback
- * @page: The page being dirtied
+ * fscache_dirty_folio - Mark folio dirty and pin a cache object for writeback
+ * @mapping: The mapping the folio belongs to.
+ * @folio: The folio being dirtied.
  * @cookie: The cookie referring to the cache object
  *
- * Set the dirty flag on a page and pin an in-use cache object in memory when
- * dirtying a page so that writeback can later write to it.  This is intended
- * to be called from the filesystem's ->set_page_dirty() method.

- *  Returns 1 if PG_dirty was set on the page, 0 otherwise.
+ * Return: true if the dirty flag was set on the folio, false otherwise.
