En el escenario de prueba de rendimiento, la funci\u00f3n irq_wait_for_interrupt() siempre devolver\u00e1 0 si se producen muchas interrupciones y la CPU se consumir\u00e1 continuamente. Como resultado, la CPU no puede ejecutar el hilo de vigilancia. Cuando el tiempo de vigilancia excede el tiempo especificado, se produce un seguimiento de llamadas. Para solucionarlo, agregue cond_resched() para ejecutar el hilo de vigilancia."
