owner-linux-mm@kvack.org Precedence: bulk X-Loop: owner-majordomo@kvack.org List-ID: commit dad6a5eb5556(mm,hugetlb: use folio fields in second tail page) added a transitional hugetlb field to struct page and struct folio to make room for another int in the first tail of a compound page. Hugetlb folio conversions have changed all page users of this field to use the fields within the folio so struct page no longer needs this hugetlb specific field.
