Message-Id: <20170719185319.25871-4-sthemmin@microsoft.com> Date: Wed, 19 Jul 2017 11:53:14 -0700 From: Stephen Hemminger <stephen@...workplumber.org> To: kys@...rosoft.com, haiyangz@...rosoft.com, sthemmin@...rosoft.com Cc: devel@...uxdriverproject.org, netdev@...r.kernel.org Subject: [PATCH net-next 3/8] netvsc: change order of steps in setting queues This fixes the error unwind logic for incorrect number of queues. If netif_set_real_num_XX_queues failed then rndis_filter_device_add would have been called twice. Since input arguments are already ranged checked this is a hypothetical only problem, not possible in actual code.
