That /proc/interrupts display requires that we maintain NR_CPUS*NR_IRQS counters. Given that a large NR_IRQs space will be sparsely populated, we should dynamically allocate the NR_CPUS storage for each active IRQ, as you say. That involves putting it into the irq_desc (as good a place as any). And a rather large number of trivial edits. I guess we do this only for genirq? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
