Not sure, why sparse is > still throwing warnings. Because there are two definitions of hugetlb_fault(): $ git grep -wn hugetlb_fault include/linux/hugetlb.h:108:vm_fault_t hugetlb_fault(struct mm_struct *mm, struct vm_area_struct *vma, include/linux/hugetlb.h:206:#define hugetlb_fault(mm, vma, addr, flags) ({ BUG(); 0; })
