    vlan: remove one synchronize_net() call · 48752e1b
    Eric Dumazet authored
    At VLAN dismantle phase, unregister_vlan_dev() makes one
    synchronize_net() call after vlan_group_set_device(grp, vlan_id, NULL).
    
    This call can be safely removed because we are calling
    unregister_netdevice_queue() to queue device for deletion, and this
    process needs at least one rcu grace period to complete.
