better. If your seccount is per-CPU then you get away without explicit
writer locking if you rely on global per-CPU locking. You can't do
preempt_disable() because this section can be interrupt by softirq. You
need something stronger :)
Side note: Adding a fixes tag and net-next looks like "stable material
starting next merge window".
