Merge branch 'arp-random-clean-up-and-rcu-conversion-for-ioctl-siocgarp'
Kuniyuki Iwashima says:
====================
arp: Random clean up and RCU conversion for ioctl(SIOCGARP).
arp_ioctl() holds rtnl_lock() regardless of cmd (SIOCDARP, SIOCSARP,
and SIOCGARP) to get net_device by __dev_get_by_name() and copy
dev->name safely.
In the SIOCGARP path, arp_req_get() calls neigh_lookup(), which looks
up a neighbour entry under RCU.
This series cleans up ioctl() code a bit and extends the RCU section
not to take rtnl_lock() and instead use dev_get_by_name_rcu() and
netdev_copy_name() for SIOCGARP.
