[PATCH 6/9] HWPOISON, hugetlb: soft offlining for hugepage
This patch extends soft offlining framework to support hugepage. When memory corrected errors occur repeatedly on a hugepage, we can choose to stop using it by migrating data onto another hugepage and disabling the original (maybe half-broken) one. ChangeLog since v1: - add double check in isolating hwpoisoned h... 10 Aug 2010 05:50

In order to handle metadatum correctly, we should check whether the hugepage we are going to access is HWPOISONed *before* incrementing mapcount, adding the hugepage into pagecache or constructing anon_vma. This patch also adds retry code when there is a race between alloc_huge_page() and memory failure. Signed-... 10 Aug 2010 05:50
