Subject: [PATCH RFC v2 for-6.8/block 08/18] bio: export bio_add_folio_nofail()

From: Yu Kuai <yukuai3@huawei.com>

Currently btrfs is using __bio_add_page() in write_dev_supers(). In order
to convert to use folio for bdev in btrfs, export bio_add_folio_nofail()
so that it can replace __bio_add_page().
