coverity flagged this code in __get_user_pages
448 if (is_vm_hugetlb_page(vma)) {
449 i = follow_hugetlb_page(mm, vma, pages, vmas,
450 &start, &nr_pages, i,
451 gup_flags);
452 continue;
453 }
It seems unaware that follow_hugetlb_page can in some cases return -EFAULT.
I'm not sure if this is triggerable, but it looks dangerous.
