Oh I see why, it's because not every arch uses the generic SMP helpers yet :-) Because if they did universally, we could solve this problem so simply, by merely sending a remote softirq to every online cpu. Once those all complete we have enough of a quiesce period, every cpu must have exited any netfilter packet processing code path they were in. And we could know they complete using an atomic counter or something. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
