Review Comment:
I noticed this change was also submitted by you earlier. So are you trying
to contradict your own previous conclusion?
https://github.com/apache/nuttx/pull/15414
In that case, I think what you should address is the atomic64 issue. Because
on 64-bit platforms, using atomic operations directly would be a more
straightforward approach.
