Applied latest two patches and re-ran the test,
hugetlb: fix potential livelock in return_unused_surplus_hugepages() hugetlb: indicate surplus huge page counts in per-node meminfo
Still same result,
>cat /proc/meminfo | grep Huge HugePages_Total: 1000 HugePages_Free: 551 HugePages_Rsvd: 1 HugePages_Surp: 0 Hugepagesize: 2048 kB
