Steven Rostedt (Red Hat) c4ecd5ed2a tracing: Prevent buffer overwrite disabled for latency tracers ...

commit 613f04a0f5 upstream.

The latency tracers require the buffers to be in overwrite mode,
otherwise they get screwed up. Force the buffers to stay in overwrite
mode when latency tracers are enabled.

Added a flag_changed() method to the tracer structure to allow
the tracers to see what flags are being changed, and also be able
to prevent the change from happing.
