[PATCH net-next 0/7] net: speedup netns create/delete time

2017-09-18 Thread Eric Dumazet
When rate of netns creation/deletion is high enough, we observe softlockups in cleanup_net() caused by huge list of netns and way too many rcu_barrier() calls. This patch series does some optimizations in kobject, and add batching to tunnels so that netns dismantles are less costly. IPv6 addrlabe
