Eric Dumazet 24b36f0193 netfilter: {ip,ip6,arp}_tables: dont block bottom half more than necessary 
We currently disable BH for the whole duration of get_counters()

On machines with a lot of cpus and large tables, this might be too long.

We can disable preemption during the whole function, and disable BH only
while fetching counters for the current cpu.
