From: Pavel Emelyanov Date: Wed, 10 Oct 2007 09:49:09 +0000 (-0700) Subject: [NET]: Remove double dev->flags checking when calling dev_close() X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9b7726523523472ead660b1d45df29dcaf6cc5c0;p=linux-beck.git [NET]: Remove double dev->flags checking when calling dev_close() The unregister_netdevice() and dev_change_net_namespace() both check for dev->flags to be IFF_UP before calling the dev_close(), but the dev_close() checks for IFF_UP itself, so remove those unneeded checks.
