[PATCH openEuler-1.0-LTS] dhugetlb: isolate hwpoison hugepage when release
by Yongqiang Liu 23 Feb '23

23 Feb '23

From: Liu Shixin <liushixin2(a)huawei.com> hulk inclusion category: bugfix bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/I6GSKP CVE: NA -------------------------------- For a hwpoison hugetlb page, the page will be freed firstly. If succeed, it will be dissolved and released to buddy system, then isolate the hwpoison page. For a hwpoison hugepage belong to dynamic hugetlb, we isolate the hugepage without dissolve it. Add a check in free_huge_page_to_dhugetlb_pool() to isolate the hwpoison hugepage directly. And keep HUGETLB_PAGE_DTOR after free to ensure the PageHuge() check return true in dissolve_free_huge_page().
