Debemos garantizar que el temporizador ya no esté activo antes de kfree(sbi). Cuando falla el montaje del sistema de archivos, el flujo va a failed_mount3, donde ocurre un error cuando se llama a ext4_stop_mmpd, lo que causa un error de E/S de lectura. Esto activa la función ext4_handle_error que, en última instancia, vuelve a armar el temporizador, dejando el temporizador s_err_report activo antes de que se llame a kfree(sbi).
