函数名称：ntp_update_offset_fll

函数原型：static inline s64 ntp_update_offset_fll(s64 offset64, long secs)

返回类型：s64

参数：

类型参数名称
s64offset64
longsecs
283  clock status bits: 与等于mode (0 = PLL, 1 = FLL) (ro) 的反
285  如果secs小于min interval between updates (s) 则返回:0
288  如果非clock status bits: 按位与select frequency-lock mode (rw) 的值且secs小于等于max interval between updates (s) 则返回:0
291  clock status bits: 或等于mode (0 = PLL, 1 = FLL) (ro)
293  返回:div64_long(offset64 << (NTP_SCALE_SHIFT - FLL frequency factor (shift) ), secs)
