be94cfdb99 dev: Hold rtnl_net_lock() for dev_ifsioc(). 
Basically, dev_ifsioc() operates on the passed single netns (except
for netdev notifier chains with lower/upper devices for which we will
need more changes).

Let's hold rtnl_net_lock() for dev_ifsioc().

Now that NETDEV_CHANGENAME is always triggered under rtnl_net_lock()
of the device's netns. (do_setlink() and dev_ifsioc())

bb9df28e6f rtnl_net_debug: Remove rtnl_net_debug_exit(). 
kernel test robot reported section mismatch in rtnl_net_debug_exit().

  WARNING: modpost: vmlinux: section mismatch in reference: rtnl_net_debug_exit+0x20 (section: .exit.text) -> rtnl_net_debug_net_ops (section: .init.data)

rtnl_net_debug_exit() uses rtnl_net_debug_net_ops() that is annotated
as __net_initdata, but this file is always built-in.

Let's remove rtnl_net_debug_exit().

Fixes: 03fa534856 ("rtnetlink: Add ASSERT_RTNL_NET() placeholder for netdev notifier.")

03fa534856 rtnetlink: Add ASSERT_RTNL_NET() placeholder for netdev notifier. 
The global and per-netns netdev notifier depend on RTNL, and its
dependency is not so clear due to nested calls.

Let's add a placeholder to place ASSERT_RTNL_NET() for each event.
