tracing: add handler to trace_stat
Currently, if a trace_stat user wants a handle to some private data, the trace_stat infrastructure does not supply a way to do that. This patch passes the trace_stat structure to the start function of the trace_stat code. Signed-off-by: Steven Rostedt <srostedt@redhat.com>
