[v1,net-next,0/3] dev: Covnert dev_change_name() to per-netns RTNL.

Patch 1 adds a missing netdev_rename_lock in dev_change_name()
and Patch 2 removes unnecessary devnet_rename_sem there.

Patch 3 replaces RTNL with rtnl_net_lock() in dev_ifsioc(),
and now dev_change_name() is always called under per-netns RTNL.

Given it's close to -rc8 and Patch 1 touches the trivial unlikely
path, can Patch 1 go into net-next ?  Otherwise I'll post Patch 2 & 3
separately in the next cycle.


Kuniyuki Iwashima (3):
  dev: Acquire netdev_rename_lock before restoring dev->name in
    dev_change_name().
  dev: Remove devnet_rename_sem.
  dev: Hold rtnl_net_lock() for dev_ifsioc().
