And since ctl_table.data is initialized later, we don't need to initialize
the data member of the template variable unix_table.

The init cost is nothing, since its a data blob that must be there
anyway.

Yes. I have tried to avoid global variable unix_table and unix_path,
then I got a bigger kernel image, so I gave it up.

We could even avoid the kmemdup() if CONFIG_NET_NS is not set

It is a good idea. We can check if the NS is init_net before kmalloc and kfree.

I'll send a update patch later. Thanks.
