If you don't use disable_irq(), the interrupt handler can run in parallel on another cpu and you definitely do not want that. There is nothing wrong with the interrupt triggering on the enable_irq() here. If that causes some problem, there is a bug in this driver. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
