Re: [PATCH net-next] tuntap: attach queue 0 before registering netdevice
From: Jason Wang jasow...@redhat.com Date: Mon, 3 Dec 2012 11:19:45 +0800 We attach queue 0 after registering netdevice currently. This leads to call netif_set_real_num_{tx|rx}_queues() after registering the netdevice. Since we allow tun/tap has a maximum of 1024 queues, this may lead a huge number of uevents to be injected to userspace since we create 2048 kobjects and then remove 2046. Solve this problem by attaching queue 0 and set the real number of queues before registering netdevice.
