From 53083773dcbd3c80477e2ace143e361e1e806745 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 17 Apr 2008 23:18:15 -0700 Subject: [INET]: Uninline the __inet_inherit_port call. This deblats ~200 bytes when ipv6 and dccp are 'y'. Besides, this will ease compilation issues for patches I'm working on to make inet hash tables more scalable wrt net namespaces.
