From e9ff3990f08e9a0c2839cc22808b01732ea5b3e4 Mon Sep 17 00:00:00 2001 From: "Serge E. Hallyn" Date: Mon, 2 Oct 2006 02:18:11 -0700 Subject: [PATCH] namespaces: utsname: switch to using uts namespaces Replace references to system_utsname to the per-process uts namespace where appropriate. This includes things like uname. Changes: Per Eric Biederman's comments, use the per-process uts namespace for ELF_PLATFORM, sunrpc, and parts of net/ipv4/ipconfig.c [jdike@addtoit.com: UML fix] [clg@fr.ibm.com: cleanup] [akpm@osdl.org: build fix] Signed-off-by: Serge E.
