y, but in this way, we only need read
lock if we operate on the item itself instead of the list.
I am not an expert in caching and golang, so please correct me if I
misunderstand anything.

or not to reclaim it at all. Neither way is friendly.

Therefore, it would be great if I can add the item to P-local storage and
flush the batched item into the lru l
