Subject: [NETNS]: Pass correct namespace in ip_rt_get_source.
X-Git-Tag: v2.6.25-rc1~1162^2~90
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ecfdc8c5424079393a9b05e8a5aaf5c6873029f6;p=linux-2.6

[NETNS]: Pass correct namespace in ip_rt_get_source.

ip_rt_get_source is the infamous place for which dst_ifdown kludges
have been implemented. This means that rt->u.dst.dev can be safely
dereferrenced obtain nd_net.
