-/**
- * try_get_compound_head() - return the compound head page with refcount
- * appropriately incremented, or NULL if that failed.
- *
- * This handles potential refcount overflow correctly. It also works correctly
- * for various lockless get_user_pages()-related callers, due to the use of
- * page_cache_add_speculative().
- *
- * Even though the name includes "compound_head", this function is still
- * appropriate for callers that have a non-compound @page to get.
- *
- * @page:  pointer to page to be gotten
- * @refs:  the value to add to the page's refcount
- *
- * Return: head page (with refcount appropriately incremented) for success, or
- * NULL upon failure.
