类型参数名称
struct trace_iterator *iter
9038  tr等于The global_trace is the descriptor that holds the top-level tracing* buffers for the live tracing.
9039  trace等于current_trace
9040  cpu_file等于RING_BUFFER_ALL_CPUS
9041  trace_buffer等于trace_buffer
9043  如果trace且open则open(iter)
9047  如果g_buffer_overruns - get the number of overruns in buffer*@buffer: The ring buffer* Returns the total number of overruns in the ring buffer* (all CPU entries)则iter_flags或等于TRACE_FILE_ANNOTATE
9051  如果 is this clock in nanoseconds? 则iter_flags或等于TRACE_FILE_TIME_IN_NS
