netfilter: nf_queue: place volatile data in own cacheline
As the comment indicates, the data at the end of nfqnl_instance struct is written on every queue/dequeue, so it should reside in its own cacheline. Before this change, 'lock' was in first cacheline so we dirtied both. Signed-off-by: NFlorian Westphal <fw@strlen.de> Signed-off-by: NPablo Neira Ayuso <pablo@netfilter.org>
