Merge branch 'tip/perf/core-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
Pull minor tracing updates and fixes from Steven Rostedt:
"It seems that one of my old pull requests have slipped through.
The changes are contained to just the files that I maintain, and are
changes from others that I told I would get into this merge window.
They have already been in linux-next for several weeks, and should be
well tested."
* 'tip/perf/core-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
tracing: Remove unnecessary WARN_ONCE's from tracing_buffers_splice_read
tracing: Remove unneeded checks from the stack tracer
tracing: Add a resize function to make one buffer equivalent to another buffer
