I am not sure what fix you suggested for this issue. The following was
sent upstream and is now included in Andrew's tree and linux-next.

https://lore.kernel.org/linux-mm/20231114012033.259600-1-mike.kravetz@oracle.com/

I tested with a reproducer previously provided by syzbot, and assume this
resolves the issue with your reproducer as well.
