函数名称:race_seq_vprintf - sequence printing of trace information*@s: trace sequence descriptor*@fmt: printf format string* The tracer may use either sequence operations or its own* copy to user routines

函数原型:void trace_seq_vprintf(struct trace_seq *s, const char *fmt, va_list args)

返回类型:void

参数:

类型参数名称
struct trace_seq *s
const char *fmt
va_listargs
146  save_len等于len
148  如果full则返回
151  race_seq should work with being initialized with 0s.
153  seq_buf_vprintf - sequence printing of information.*@s: seq_buf descriptor*@fmt: printf format string*@args: va_list of arguments from a printf() type function* Writes a vnprintf() format into the sequencce buffer.* Returns zero on success, -1 on overflow.
156  如果此条件成立可能性小(为编译器优化)(seq_buf have a buffer that might overflow. When this happens* the len and size are set to be equal.)则
157  len等于save_len
158  full等于1
