Some treat the\niterator as struct rv_monitor *, while others treat the iterator as struct\nlist_head *.\n\nThis causes a wrong type cast and crashes the system as reported by Nathan.\n\nConvert everything to use struct list_head * as iterator. This also makes\nenabled_monitors consistent with available_monitors."

Algunas tratan el iterador como struct rv_monitor *, mientras que otras tratan el iterador como struct list_head *.\n\nEsto causa una conversión de tipo incorrecta y bloquea el sistema, según lo informado por Nathan.\n\nConvertir todo para usar struct list_head * como iterador. Esto también hace que enabled_monitors sea consistente con available_monitors."
