- * page_is_file_cache - should the page be on a file LRU or anon LRU?
+ * page_is_file_lru - should the page be on a file LRU or anon LRU?
* @page: the page to test
*
- * Returns 1 if @page is page cache page backed by a regular filesystem,
- * or 0 if @page is anonymous, tmpfs or otherwise ram or swap backed.
- * Used by functions that manipulate the LRU lists, to sort a page
- * onto the right LRU list.
+ * Returns 1 if @page is a regular filesystem backed page cache page or a lazily
+ * freed anonymous page (e.g. via MADV_FREE). Returns 0 if @page is a normal
+ * anonymous page, a tmpfs page or otherwise ram or swap backed page. Used by
+ * functions that manipulate the LRU lists, to sort a page onto the right LRU
+ * list.
*
* We would like to get this info without a page flag, but the state
* needs to survive until the page is last deleted from the LRU, which
* could be as far down as __page_cache_release.
