- * This is subtle. The timer interrupt is crucial and it should not be disabled
- * for too long. However, if it had been a normal interrupt as per BUILD_IRQ, it
- * would have been BLOCK'ed, and then softirq's are run before we return here to
- * UNBLOCK. If the softirq's take too much time to run, the timer irq won't run
- * and the watchdog will kill us.
- *
- * Furthermore, if a lot of other irq's occur before we return here, the
- * multiple_irq handler is run and it prioritizes the timer interrupt. However
- * if we had BLOCK'edit here, we would not get the multiple_irq at all.
- *
- * The non-blocking here is based on the knowledge that the timer interrupt is
- * registred as a fast interrupt (IRQF_DISABLED) so that we _know_ there will not
- * be an sti() before the timer irq handler is run to acknowledge the interrupt.
