Thanks for the hint Andy. I do very much prefer using stuff like the DIV_ROUND_CLOSEST_ULL().

I will use this - do you have other suggestions for me, especially regarding the division u64 / u64?

I would appreciate if you found the time and energy to look at:
https://lore.kernel.org/all/ZUDN9n8iXoNwzifQ@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/
as well. I feel like I am doing something someone else has already done. (Yes, DIV_ROUND_CLOSEST_ULL() can be used there too).

Anyways, Thanks for this!

Yours,
