      rtnelink: Move link dump consistency check out of the loop · d0225784
      Jakub Sitnicki authored
      Calls to rtnl_dump_ifinfo() are protected by RTNL lock. So are the
      {list,unlist}_netdevice() calls where we bump the net->dev_base_seq
      number.
      
      For this reason net->dev_base_seq can't change under out feet while
      we're looping over links in rtnl_dump_ifinfo(). So move the check for
      net->dev_base_seq change (since the last time we were called) out of the
      loop.
      
      This way we avoid giving a wrong impression that there are concurrent
      updates to the link list going on while we're iterating over them.
