  .resume - A pointer to a per-policy resume function which is called
  with interrupts disabled and _before_ the governor is started again.
 
- .ready - A pointer to a per-policy ready function which is called after
- the policy is fully initialized.
-
  .attr - A pointer to a NULL-terminated list of "struct freq_attr" which
  allow to export values to sysfs.

  .resume - 一个指向per-policy恢复函数的指针，该函数在关中断且在调节器再一次开始前被
  调用。
