tracing: Pass the trace_array into ftrace_probe_ops functions
Pass the trace_array associated to a ftrace_probe_ops into the probe_ops func(), init() and free() functions. The trace_array is the descriptor that describes a tracing instance. This will help create the infrastructure that will allow having function probes unique to tracing instances. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
