From: Joanne Koong <joannelkoong@gmail.com> To pave the way for refactoring out the shared logic in fuse_writepages_fill() and fuse_writepage_locked(), this change converts the temporary page in fuse_writepages_fill() to use the folio API. This is similar to the change in commit e0887e095a80 ("fuse: Convert fuse_writepage_locked to take a folio"), which converted the tmp page in fuse_writepage_locked() to use the folio API. inc_node_page_state() is intentionally preserved here instead of converting to node_stat_add_folio() since it is updating the stat of the underlying page and to better maintain API symmetry with dec_node_page_stat() in fuse_writepage_finish_stat(). No functional changes added.
