netns: add register_pernet_gen_subsys/unregister_pernet_gen_subsys
netns ops which are registered with register_pernet_gen_device() are shutdown strictly before those which are registered with register_pernet_subsys(). Sometimes this leads to opposite (read: buggy) shutdown ordering between two modules. Add register_pernet_gen_subsys()/unregister_pernet_gen_subsys() for modules which aren't elite enough for entry in struct net, and which can't use register_pernet_gen_device(). PPTP conntracking module is such one. Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
