函数原型：static __always_inline void timekeeping_apply_adjustment(struct timekeeper *tk, s64 offset, s32 mult_adj)

返回类型：void

参数：

类型参数名称
struct timekeeper *tk
s64offset
s32mult_adj
1825  interval等于The following members are for timekeeping internal use
1827  如果mult_adj恒等于0则
1828  返回
1829  否则如果mult_adj恒等于负1则
1830  interval等于负interval
1831  offset等于负offset
1832  否则如果mult_adj不等于1则
1833  interval乘等于mult_adj
1834  offset乘等于mult_adj
1884  如果mult_adj大于0且mult加mult_adj小于mult_adj则
1886  WARN_ON_ONCE(1)
1887  返回
1890  mult加等于mult_adj
1891  xtime_interval加等于interval
1892  xtime_nsec减等于offset
