返回类型：int

参数：

类型参数名称
struct trace_seq *s
struct probe_arg *args
intnr_args
u8 *data
void *field
223  以i小于nr_args循环
224  a等于args加i
226  race_seq_printf - 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
227  如果此条件成立可能性大(为编译器优化)(! Array count )则
228  如果非Print functions (s, data + Offset from argument entry , field)则返回:负ENOMEM
230  继续下一循环
232  race_seq_putc - trace sequence printing of simple character*@s: trace sequence descriptor*@c: simple character to record* The tracer may use either the sequence operations or its own* copy to user routines
233  p等于data加 Offset from argument entry
234  以j小于 Array count 循环
235  如果非Print functions (s, p, field)则返回:负ENOMEM
237  race_seq_putc - trace sequence printing of simple character*@s: trace sequence descriptor*@c: simple character to record* The tracer may use either the sequence operations or its own* copy to user routines
238  p加等于Byte size of type
241  返回:0
