函数名称：trace_print_flags_seq

函数原型：const char *trace_print_flags_seq(struct trace_seq *p, const char *delim, unsigned long flags, const struct trace_print_flags *flag_array)

返回类型：char

参数：

类型参数名称
struct trace_seq *p
const char *delim
unsigned longflags
const struct trace_print_flags *flag_array
71  ret等于race_seq_buffer_ptr - return pointer to next location in buffer*@s: trace sequence descriptor* Returns the pointer to the buffer where the next write to* the buffer will happen
72  first等于1
74  以name且flags循环
76  mask等于mask
77  如果flags按位与mask的值不等于mask则继续下一循环
80  str等于name
81  flags与等于mask的反
82  如果非first且delim则trace_seq_puts(p, delim)
84  否则first等于0
86  trace_seq_puts(p, str)
90  如果flags则
91  如果非first且delim则trace_seq_puts(p, delim)
93  Currently only defined when tracing is enabled.
96  trace_seq_putc(p, 0)
98  返回:ret
