tracing: Kill unused and puzzled sample code in ftrace.h
When doing per-cpu helper optimizing work, find that this code is so puzzled. 1. It's mark as comment text, maybe a sample function for guidelines or a todo work. 2. But, this sample code is odd where struct perf_trace_buf is nonexistent. commit ce71b9 delete struct perf_trace_buf definition. Author: Frederic Weisbecker <fweisbec@gmail.com> Date: Sun Nov 22 05:26:55 2009 +0100 tracing: Use the perf recursion protection from trace event Is it necessary to keep there? just compile test.
