Hallyn Date: Mon, 2 Oct 2006 09:18:13 +0000 (-0700) Subject: [PATCH] namespaces: utsname: use init_utsname when appropriate X-Git-Tag: v2.6.19-rc1~412 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=96b644bdec977b97a45133e5b4466ba47a7a5e65;p=linux-2.6 [PATCH] namespaces: utsname: use init_utsname when appropriate In some places, particularly drivers and __init code, the init utsns is the appropriate one to use. This patch replaces those with a the init_utsname helper. Changes: Removed several uses of init_utsname(). Hope I picked all the right ones in net/ipv4/ipconfig.c. These are now changed to utsname() (the per-process namespace utsname) in the previous patch (2/7) [akpm@osdl.org: CIFS fix] Signed-off-by: Serge E. Hallyn Cc: Kirill Korotaev Cc: "Eric W.
