From 931731123a103cfb3f70ac4b7abfc71d94ba1f03 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 9 Nov 2006 19:58:25 -0800 Subject: [TCP]: Don't set SKB owner in tcp_transmit_skb(). The data itself is already charged to the SKB, doing the skb_set_owner_w() just generates a lot of noise and extra atomics we don't really need. Lmbench improvements on lat_tcp are minimal: before: TCP latency using localhost: 23.2701 microseconds TCP latency using localhost: 23.1994 microseconds TCP latency using localhost: 23.2257 microseconds after: TCP latency using localhost: 22.8380 microseconds TCP latency using localhost: 22.9465 microseconds TCP latency using localhost: 22.8462 microseconds Signed-off-by: David S.
