From abbdb5a74cead60e20b79c960c1772955f0b6b81 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 20 Mar 2016 11:27:47 -0700 Subject: [PATCH] net: remove a dubious unlikely() clause TCP protocol is still used these days, and TCP uses clones in its transmit path. We can not optimize linux stack assuming it is mostly used in routers, or that TCP is dead.
