   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.
