From 86b3bfe914f41c2d47d5882d06e1261cc58fb5e9 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 28 Jan 2015 06:06:36 -0800 Subject: pkt_sched: fq: remove useless TIME_WAIT check TIME_WAIT sockets are not owning any skb. ip_send_unicast_reply() and tcp_v6_send_response() both use regular sockets. We can safely remove a test in sch_fq and save one cache line miss, as sk_state is far away from sk_pacing_rate. Tested at Google for about one year.
