[PATCH 2/7] uts namespaces: switch to using uts namespaces
From: Serge E. Hallyn
Date: Mon May 01 2006 - 15:56:04 EST
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
