The bigger problem is that the sysctl's aren't documented very well.
Can you come up with a patch to help document these better? Either in
sysctl(8), or tuning(7), or anywhere else? kern.smp.* only shows up
on SMP aware kernels, so I don't really see this as that big of a
problem. If you're interested, please work with Tom Rhodes and the
doc team on finding the best place to document these different sysctl
Personally, I think this PR should be closed, but I'd appreciate any
help you could give us on the larger sysctl documentation problem.
