This patch changes conntrack to use the new mod_timer_pending()
function, which only rearms the timer if it was still active.
This allows to only grab the lock in __nf_ct_refresh_acct when
accounting is used.
Anyone seing anything wrong with this?
if (acct) {
+ spin_lock_bh(&nf_conntrack_lock);
acct[CTINFO2DIR(ctinfo)].packets++;
acct[CTINFO2DIR(ctinfo)].bytes +=
skb->len - skb_network_offset(skb);
+ spin_unlock_bh(&nf_conntrack_lock);
}
In fact, we could additionally change it to use the per-conntrack lock.
