Should I use the pernet stuff for rxrpc sysctls

[David Howells]

I also noticed this in net/core/sysctl_net_core.c:

	static struct ctl_table net_core_table[] = {
	#ifdef CONFIG_NET  <---
		{

But isn't the content of the net/core/ directory contingent on CONFIG_NET=y in
net/Makefile, rendering this redundant?
