Eric Dumazet 7f5c6d4f66 netfilter: get rid of atomic ops in fast path ... We currently use a percpu spinlock to 'protect' rule bytes/packets counters, after various attempts to use RCU instead. Lately we added a seqlock so that get_counters() can run without blocking BH or 'writers'. But we really only need the seqcount in it. Spinlock itself is only locked by the current/owner cpu, so we can remove it completely. This cleanups api, using correct 'writer' vs 'reader' semantic. At replace time, the get_counters() call makes sure all cpus are done using the old table.
