Patch 1 add some bdev apis, then follow up patches will use these apis
to avoid access bd_inode directly, and hopefully the field bd_inode can
be removed eventually(after figure out a way for fs/buffer.c).

Yu Kuai (14):
block: add some bdev apis
xen/blkback: use bdev api in xen_update_blkif_status()
bcache: use bdev api in read_super()
mtd: block2mtd: use bdev apis
s390/dasd: use bdev api in dasd_format()
scsicam: use bdev api in scsi_bios_ptable()
bcachefs: remove dead function bdev_sectors()
btrfs: use bdev apis
cramfs: use bdev apis in cramfs_blkdev_read()
erofs: use bdev api
ext4: use bdev apis
jbd2: use bdev apis
gfs2: use bdev api
nilfs2: use bdev api in nilfs_attach_log_writer()
