    commit d1a5f2b4 ("block: use DAX for partition table reads") was
    part of a stalled effort to allow dax mappings of block devices. Since
    then the device-dax mechanism has filled the role of dax-mapping static
    device ranges.
    
    Now that we are moving ->direct_access() from a block_device operation
    to a dax_inode operation we would need block devices to map and carry
    their own dax_inode reference.
    
    Unless / until we decide to revive dax mapping of raw block devices
    through the dax_inode scheme, there is no need to carry
    read_dax_sector(). Its removal in turn allows for the removal of
    bdev_direct_access() and should have been included in commit
    22375701 ("block_dev: remove DAX leftovers").
