Subject: [PATCH net-next 0/2] rtnetlink: rtnl_stats_dump() changes

Getting rid of RTNL in rtnl_stats_dump() looks challenging.

In the meantime, we can:

1) Avoid RTNL acquisition for the final NLMSG_DONE marker.

2) Use for_each_netdev_dump() instead of the net->dev_index_head[]
   hash table.

Eric Dumazet (2):
  rtnetlink: change rtnl_stats_dump() return value
  rtnetlink: use for_each_netdev_dump() in rtnl_stats_dump()
