  "message": "net: Introduce dev_get_by_name_rcu()\n\nSome workloads hit dev_base_lock rwlock pretty hard.\nWe can use RCU lookups to avoid touching this rwlock\n(and avoid touching netdevice refcount)\n\nnetdevices are already freed after a RCU grace period, so this patch\nadds no penalty at device dismantle time.\n\nHowever, it adds a synchronize_rcu() call in dev_change_name()\n\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.
