hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TL9N CVE: NA

--------------------------------

Before commit 738fe30dc41a, the PG_hugetlb is recorded in page->flags, and will be cleared by clear_compound_page(). Now since PG_hugetlb turned to record into page_type, we have to clear it by __folio_clear_hugetlb().
