Subject: [PATCH v8 0/3] mm/hwpoison: fix race between hugetlb free/demotion and memory_failure_hugetlb()

Hi,

I updated v7 (https://lore.kernel.org/linux-mm/20220407112929.1344748-1-naoya.horiguchi@linux.dev/)
based on the comment from Miaohe Lin.  Now I have a few additional patches.
Any comments and suggestions are welcomed.

Thanks,
Naoya Horiguchi
