[for-next][PATCH 0/4] tracing: Cleanups and fixes for 3.16

[Steven Rostedt <rostedt@goodmis.org>]

Thanks to Namhyung Kim who pointed out some slight things with the code
that went to Linus already, I have some early cleanups.

There's also a bug that needs to be fixed in the ring buffer waiter
logic.
