      IPoIB: Fix deadlock between ipoib_open() and child interface create · cbbe1efa
      Roland Dreier authored
      Fix a deadlock between child interface creation/deletion and ipoib
      start/stop.  The former takes vlan_mutex, and then might take RTNL via
      register_netdev()/unregister_netdev().  The latter is executed with
      RTNL held, and tries to take vlan_mutex, which can lead to an AB-BA
      deadlock.
      
      Fix this by having the child interface creation/deletion code take the
      RTNL first so vlan_mutex always nests inside RTNL.  We can use
      register_netdevice() for child interfaces because we form the
      interface name from the parent interface and hence don't need the '%'
      expansion of register_netdev().
