[PATCH net-next can] Converting pernet_operations (part #9)

[Kirill Tkhai]

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 is only one patch converting
can_pernet_ops.

Thanks,
Kirill

[PATCH net-next] net: Convert can_pernet_ops

[Kirill Tkhai]

These pernet_operations create and destroy /proc entries
and cancel per-net timer.

Also, there are unneed iterations over empty list of net
devices, since all net devices must be already moved
to init_net or unregistered by default_device_ops. This
already was mentioned here:

https://marc.info/?l=linux-can&m=150169589119335&w=2

So, it looks safe to make them async.
