Definitely. I'm not for a minute arguing that the nfsservctl-style thing
is not how it should be done for those cases.

I'll genuinely take on board advice on how I can profile all the system
via x86 perf counters efficiently without having to patch the kernel.
The old way just uses sys_call_table. So what do I do now ?

I've actually *tried* doing the /proc-reading thing. It's very low
resolution and/or too slow.
