Subject: [RTNL]: Relax for_each_netdev_safe in __rtnl_link_unregister.
X-Git-Tag: v2.6.26-rc1~1138^2~63
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3a931a80cb25f905da377d1bb0ba9b1641aa579a;p=linux-2.6-omap-h63xx.git

[RTNL]: Relax for_each_netdev_safe in __rtnl_link_unregister.

Each potential list_del (happening from inside a ->dellink call)
is followed by goto restart, so there's no need in _safe iteration.
