[git pull] vfs bdev pile 2

[Al Viro <viro@zeniv.linux.org.uk>]

	Next block device series - replacing ->bd_inode (me and Yu Kuai).
Two trivial conflicts (block/ioctl.c and fs/btrfs/disk-io.c); proposed
resolution in #merge-candidate (or in linux-next, for that matter).

The following changes since commit d18a8679581e8d1166b68e211d16c5349ae8c38c:

  make set_blocksize() fail unless block device is opened exclusive (2024-05-02 17:39:44 -0400)

  RIP ->bd_inode (2024-05-03 02:36:56 -0400)

----------------------------------------------------------------
	bd_inode series

Replacement of bdev->bd_inode with sane(r) set of primitives.

----------------------------------------------------------------
Al Viro (16):
      erofs: switch erofs_bread() to passing offset instead of block number
      erofs_buf: store address_space instead of inode
      blkdev_write_iter(): saner way to get inode and bdev
      dm-vdo: use bdev_nr_bytes(bdev) instead of i_size_read(bdev->bd_inode)
      missing helpers: bdev_unhash(), bdev_drop()
      Merge branch 'misc.erofs' into work.bdev
      block_device: add a pointer to struct address_space (page cache of bdev)
      use ->bd_mapping instead of ->bd_inode->i_mapping
      grow_dev_folio(): we only want ->bd_inode->i_mapping there
      blk_ioctl_{discard,zeroout}(): we only want ->bd_inode->i_mapping here...
      fs/buffer.c: massage the remaining users of ->bd_inode to ->bd_mapping
      gfs2: more obvious initializations of mapping->host
      block/bdev.c: use the knowledge of inode/bdev coallocation
      nilfs_attach_log_writer(): use ->bd_mapping->host instead of ->bd_inode
      dasd_format(): killing the last remaining user of ->bd_inode
      RIP ->bd_inode

Yu Kuai (4):
      ext4: remove block_device_ejected()
      bcachefs: remove dead function bdev_sectors()
      block2mtd: prevent direct access of bd_inode
      block: move two helpers into bdev.c
