linux-next/Documentation/trace
Linus Torvalds 68114e5eb8 Most of the changes were largely clean ups, and some documentation.
But there were a few features that were added.
 
 Uprobes now work with event triggers and multi buffers.
 Uprobes have support under ftrace and perf.
 
 The big feature is that the function tracer can now be used within the
 multi buffer instances. That is, you can now trace some functions
 in one buffer, others in another buffer, all functions in a third buffer
 and so on. They are basically agnostic from each other. This only
 works for the function tracer and not for the function graph trace,
 although you can have the function graph tracer running in the top level
 buffer (or any tracer for that matter) and have different function tracing
 going on in the sub buffers.
