net: Introduce dev_get_by_index_rcu()
Some workloads hit dev_base_lock rwlock pretty hard. We can use RCU lookups to avoid touching this rwlock. netdevices are already freed after a RCU grace period, so this patch adds no penalty at device dismantle time. dev_ifname() converted to dev_get_by_index_rcu() Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
