[PATCH v13 06/12] mm: hugetlb: set the PageHWPoison to the raw error page

2021-01-17 Thread Muchun Song
Because we reuse the first tail vmemmap page frame and remap it with read-only, we cannot set the PageHWPosion on a tail page. So we can use the head[4].private to record the real error page index and set the raw error page PageHWPoison later. Signed-off-by: Muchun Song Reviewed-by: Oscar Salvado
