[PATCH 0/2] tracing/stat handling updates

[Frederic Weisbecker]

After a quick look on the need of stats tracers, it looks like it is often
needed to have several stat modes/files for a single tracer.

The current tracing stat API doesn't support more than one stat file per tracer.

The first patch makes the tracing/stat Api reentrant and let a tracer able
implement more than one stat file.

The second one adapts this Api to the branch tracer.
