函数名称：Add two ktime values and do a safety check for overflow:

函数原型：ktime_t ktime_add_safe(const ktime_t lhs, const ktime_t rhs)

返回类型：ktime_t

参数：

类型参数名称
const ktime_tlhs
const ktime_trhs
325  res等于Same as ktime_add(), but avoids undefined behaviour on overflow; however,* this means that you must check the result for overflow yourself.(lhs, rhs)
331  如果res小于0或res小于lhs或res小于rhs则res等于ktime_set - Set a ktime_t variable from a seconds/nanoseconds value*@secs: seconds to set*@nsecs: nanoseconds to set* Return: The ktime_t representation of the value.
334  返回:res
