tracing: Add disable_on_free option
Add a trace option to disable tracing on free. When this option is set, a write into the free_buffer file will not only shrink the ring buffer down to zero, but it will also disable tracing. Cc: Vaibhav Nagarnaik <vnagarnaik@google.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
