Sin embargo, las publicaciones pueden residir en un lote de publicaciones sin el indicador LRU establecido o tener su indicador LRU borrado temporalmente. En consecuencia, la bandera LRU no es fiable para este fin. En particular, este es el caso cuando secretmem_fault() asigna una página nueva y llama a filemap_add_folio()->folio_add_lru(). La publicación podría agregarse al lote de publicaciones por CPU y no se establecerá el indicador LRU hasta que el lote se drene usando, por ejemplo, lru_add_drain(). En consecuencia, es posible que folio_is_secretmem() no detecte folios secretmem y GUP-fast puede lograr capturar un folio secretmem, bloqueando el kernel cuando más tarde intentemos leer/escribir en el folio, porque el folio no se ha desasignado del mapa directo.
