Subject: ipv4: Get peer more cheaply in rt_init_metrics().
X-Git-Tag: v2.6.39-rc1~468^2~155
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3c0afdca44af795dd315c20cc525927a459abe30;p=platform%2Fkernel%2Flinux-3.10.git

ipv4: Get peer more cheaply in rt_init_metrics().

We know this is a new route object, so doing atomics and
stuff makes no sense at all.
