Convert __lock_page_or_retry() to __folio_lock_or_retry(). This actually saves 4 bytes in the only caller of lock_page_or_retry() (due to better register allocation) and saves the 14 byte cost of calling page_folio() in __folio_lock_or_retry() for a total saving of 18 bytes. Also use a bool for the return type.
