This patch starts to convert pernet_subsys, registered
from core initcalls.
Since net/socket.o is the first linked file in net/Makefile,
its core initcalls execute the first. sysctl_pernet_ops is
the first pernet_subsys, registered from sock_init(), so
it goes ahead of others, registered via core_initcall().
Methods sysctl_net_init() and sysctl_net_exit() initialize
net::sysctls of a namespace.
pernet_operations::init()/exit() methods from the rest
of the list do not touch net::sysctls of strangers,
so it's safe to execute sysctl_pernet_ops's methods
in parallel with any other pernet_operations.
