that means nothing runs in ksoftirqd for Dipankar, so he cannot be using

Either that or I'm misreading his numbers, or his stats results are wrong.

If these numbers are with your "if (ksoftirqd_pending()) return;" thing
at the top of do_softirq() then I must agree with you.

Otherwise, keep in mind what I said, and also as Robert mentioned every
single local_bh_enable() is going to call do_softirq() if the count falls
to zero.
