Ignore the latter point - I realize that I can use ring_buffer_alloc,
etc. quite happily. I am doing that now in my smi_detector rewrite. But
I still think the RB is a little too tracing specific - so, perhaps we
can move it out of kernel/trace. I'll write up something once I've
figured out this stuff to go along with the excellent trace docs since
the generic ring buffer implementation is really quite sexy stuff.

[thinking out loud] Does the global disable stuff also disable other
non-tracing ring buffers?

Jon.
