| |
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.
