1651  tr等于The global tracer (top) should be the first trace array added,* but we check the flag anyway.
1656  mutex_lock( & event_mutex)
1657  r_each_trace_kprobe - iterate over the trace_kprobe list*@pos: the struct trace_kprobe * for each entry*@dpos: the struct dyn_event * to use as a loop cursor(tk, pos)
1658  list_for_each_entry - iterate over list of given type*@pos: the type * to use as a loop cursor.*@head: the head for your list.*@member: the name of the list_head within the struct.(file, & events, list)
1659  如果event_call恒等于trace_probe_event_call( & tp)则trace_event_enable_disable(file, 1, 0)
