Consider having 100,000 DCCP sockets, some large percentage of which are polling in this manner, it simply doesn't scale. And if anything this return value should be jiffies_to_msecs(1) or something like that. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
