Here we iterate for_each_net() and removes
vport from alive net to the exiting net.
ovs_net::dps are protected by ovs_mutex(),
and the others, who change it (ovs_dp_cmd_new(),
__dp_destroy()) also take it.
The same with datapath::ports list.
So, we remove rtnl_lock() here.

rtnl_lock() doesn't protect net::ct::count,
and it's not needed for__nf_ct_unconfirmed_destroy()
and for nf_queue_nf_hook_drop().

that can change the order, but since skb can be queued
in any order, it doesn't matter, how many threads do this
in parallel. In case of several threads, this will be even
faster.
So, we can remove rtnl_lock() here, as it was used for
iteration over net_namespace_list only.

emove rtnl_lock() there are
in next patches.
Fine grained locks generally are better, then one big lock,
so let's do that with net_namespace_list, while the situation
allows that.

These pernet_operations register and unregister ipvs app.
register_ip_vs_app(), unregister_ip_vs_app() and
register_ip_vs_app_inc() modify per-net structures,
and there are no global structures touched. So,
this looks safe to be marked as async.

Exit method stops two per-net threads and cancels
delayed work. Everything looks nicely per-net divided.

were possible several timer expirations before this
patch, and since they are safe, the patch does not invent
new parallelism of their destruction. These pernet_operations
look safe to be converted.

These pernet_operations register and unregister sysctl table.
Exit methods frees platform_labels from net::mpls::platform_label.
Everything is per-net, and they looks safe to be marked async.

Hi,
this series continues to review and to convert pernet_operations
to make them possible to be executed in parallel for several
net namespaces at the same time. There are different operations
over the tree, mostly are ipvs.
Thanks,
Kirill

net: Convert l2tp_net_ops
Init method is rather simple. Exit method queues del_work
for every tunnel from per-net list. This seems to be safe
to be marked async.
