函数名称：Update the ktime_t based scalar nsec members of the timekeeper

函数原型：static inline void tk_update_ktime_data(struct timekeeper *tk)

返回类型：void

参数：

类型参数名称
struct timekeeper *tk
642  seconds等于xtime_sec加 seconds
643  nsec等于 nanoseconds
644  base等于ns_to_ktime(seconds * NSEC_PER_SEC + nsec)
651  nsec加等于xtime_nsec右移shift位
652  如果nsec大于等于NSEC_PER_SEC则seconds自加
654  ktime_sec等于seconds
657  base等于ns_to_ktime(raw_sec * NSEC_PER_SEC)
