Sender: owner-linux-mm@kvack.org Precedence: bulk X-Loop: owner-majordomo@kvack.org List-ID: List-Subscribe: List-Unsubscribe: f2fs sets its PAGE_PRIVATE_* flags in page->private and checking page->private != NULL is equivalent to checking PG_private. Change PagePrivate() to page_private(). Meanwhile, in set_page_private_##name(), page->private is first set to 0/NULL before an PAGE_PRIVATE_* flag is set, but it can cause confusion when PG_private is removed and page->private != NULL is used instead. Change it to initialize page->private to PAGE_PRIVATE_NOT_POINTER instead and retain the original semantics. It prepares for a future commit that removes PG_private. No functional change intended.
