From 9b7726523523472ead660b1d45df29dcaf6cc5c0 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 10 Oct 2007 02:49:09 -0700 Subject: [PATCH] [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.
