From 39d8cda76cfb1178455f9d196b39e773878e6c05 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sat, 22 Mar 2008 16:50:58 -0700 Subject: [SOCK]: Add udp_hash member to struct proto. Inspired by the commit ab1e0a13 ([SOCK] proto: Add hashinfo member to struct proto) from Arnaldo, I made similar thing for UDP/-Lite IPv4 and -v6 protocols. The result is not that exciting, but it removes some levels of indirection in udpxxx_get_port and saves some space in code and text. The first step is to union existing hashinfo and new udp_hash on the struct proto and give a name to this union, since future initialization of tcpxxx_prot, dccp_vx_protinfo and udpxxx_protinfo will cause gcc warning about inability to initialize anonymous member this way.
