Date: Thu, 17 Jul 2014 19:46:09 +0200 From: Veaceslav Falico <vfalico@...il.com> To: netdev@...r.kernel.org Cc: Veaceslav Falico <vfalico@...il.com>, "David S. Miller" <davem@...emloft.net>, Tom Gundersen <teg@...m.no> Subject: [PATCH v3 net-next 1/2] net: use dev->name in netdev_pr* when it's available netdev_name() returns dev->name only when the net_device is in NETREG_REGISTERED state. However, dev->name is always populated on creation, so we can easily use it. There are two cases when there's no real name - when it's an empty string or when the name is in form of "eth%d", then netdev_name() returns "unnamed net_device". CC: "David S.
