Re: [v5 PATCH 6/6] mm: hwpoison: handle non-anonymous THP correctly

A related bug but whose fix may belong to a separate series:

split_huge_page fails when invoked concurrently on the same THP page.

It's possible that multiple memory errors on the same THP get consumed
by multiple threads and come down to split_huge_page path easily.

Thanks,
