Esta serie de correcci\u00f3n de errores cubre tres problemas relacionados con el escritor de registros nilfs2, incluido un problema de use-after-free del temporizador y un posible problema de bloqueo al desmontar, y un posible problema de congelaci\u00f3n en la sincronizaci\u00f3n de eventos encontrado durante su an\u00e1lisis. Los detalles se describen en cada registro de confirmaci\u00f3n. Este parche (de 3): Se inform\u00f3 un problema de use-after-free con respecto al temporizador sc_timer en la estructura nilfs_sc_info. El problema es que, aunque se utiliza para reactivar un subproceso de escritura de registros inactivo, sc_timer no se cierra hasta que la estructura nilfs_sc_info est\u00e1 a punto de liberarse y se utiliza independientemente de la vida \u00fatil del subproceso.
