To a certain extent, yes, and that is why this kind of patch needs a lot of testing. But to be honest, TCP is a lot less sensitive to the RCU latencies than things like the routing cache are, so I really don't expect any real problems in this area. You cannot create one full-fledged TCP socket per packet, but you can create a new routing cache entry per packet :-) - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
