384  save_len等于len
386  如果full则返回:0
389  race_seq should work with being initialized with 0s.
391  如果How much buffer is left on the trace_seq? (s)小于1则
392  full等于1
393  返回:0
396  seq_buf_hex_dump - print formatted hex dump into the sequence buffer*@s: seq_buf descriptor*@prefix_str: string to prefix each line with;* caller supplies trailing spaces for alignment if desired*@prefix_type: controls whether prefix of an offset,
400  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
401  len等于save_len
402  full等于1
403  返回:0
406  返回:1
