参数：

类型参数名称
unsigned longsetpoint dirty 3
unsigned longdirty
unsigned longlimit setpoint
819  x等于div64_s64 - signed 64bit divide with 64bit divisor*@dividend: 64bit dividend*@divisor: 64bit divisor
821  pos_ratio等于x
822  pos_ratio等于pos_ratio乘x右移RATELIMIT_CALC_SHIFT位
823  pos_ratio等于pos_ratio乘x右移RATELIMIT_CALC_SHIFT位
824  pos_ratio加等于1左移RATELIMIT_CALC_SHIFT位
826  返回:clamp - return a value clamped to a given range with strict typechecking*@val: current value*@lo: lowest allowable value*@hi: highest allowable value* This macro does strict typechecking of @lo/@hi to make sure they are of the* same type as @val(pos_ratio, 0LL, 2LL << RATELIMIT_CALC_SHIFT)
