函数名称：trace_print_symbols_seq_u64

函数原型：const char *trace_print_symbols_seq_u64(struct trace_seq *p, unsigned long long val, const struct trace_print_flags_u64 *symbol_array)

返回类型：char

参数：

类型参数名称
struct trace_seq *p
unsigned long longval
const struct trace_print_flags_u64 *symbol_array
171  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
173  以name循环
175  如果val不等于mask则继续下一循环
178  trace_seq_puts(p, name)
179  退出
182  如果ret恒等于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则Currently only defined when tracing is enabled.
185  trace_seq_putc(p, 0)
187  返回:ret
