agreed.

I'm thinking that we could keep:

  TRACEPOINT_EVENT()/tracepoint() for the production-style
instrumentation. It is meant to be well-thought anyway, so it does not
hurt if it takes a bit more time to type in.

For debug-style instrumentation, trace_printf() looks really
interesting, and I don't find matches with google (the first matches are
trace_printk(), in the kernel).

Thoughts ?
