[PATCH 0/3] correct the parameter type of some mm functions

[Qi Zheng <qi.zheng@linux.dev>]

From: Qi Zheng <zhengqi.arch@bytedance.com>

Hi all,

As Harry Yoo pointed out [1], in the case of reparenting LRU folios, the value
passed to functions such as __mod_memcg{_lruvec}_state() may exceed the upper
limit of int, so this series aims to correct the parameter type of these
functions.

This series is based on the next-20260323.

Comments and suggestions are welcome!

Thanks,
Qi
