[PATCH] namespaces: utsname: switch to using uts namespaces
Serge E. Hallyn [Mon, 2 Oct 2006 09:18:11 +0000 (02:18 -0700)]
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
