Where are interrupts disabled? I just went through a set of kernprof data and traced up the call graph. In the most common __kfree_skb case, I do not believe that it has interupts disabled. I could be wrong, but I didn't see it.
That's completely right. interrupts should never be disabled when __kfree_skb is executed. It used to be possible when we allowed it to be invoked from interrupt handlers, but that is illegal and we have kfree_skb_irq which just reschedules the actual __kfree_skb to a software interrupt.
So I agree with you, Mala's claims seem totally bogus and not well founded at all. - 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/
