Kirill Tkhai Nov. 20, 2017, 6:33 p.m. UTC 
This patch starts to convert pernet_subsys, registered
from before initcalls.

proc_net_ns_ops::proc_net_ns_init()/proc_net_ns_exit()
register pernet net->proc_net and ->proc_net_stat.

Constructors and destructors of another pernet_operations
are not interested in foreign net's proc_net and proc_net_stat.
Proc filesystem privitives are synchronized on proc_subdir_lock.

So, proc_net_ns_ops methods are able to be executed
in parallel with methods of other pernet operations.
