Synopsis

struct hrtimer {
  struct rb_node node;
  ktime_t expires;
  enum hrtimer_restart		(* function) (struct hrtimer *);
  struct hrtimer_clock_base * base;
  unsigned long state;
  enum hrtimer_cb_mode cb_mode;
  struct list_head cb_entry;
#ifdef CONFIG_TIMER_STATS
  void * start_site;
  char start_comm[16];
  int start_pid;
#endif
};
