Ext4 mount path calls .bmap to the journal inode. This currently works for the DAX mount case because ext4_iget() always set 'ext4_da_aops' to any regular files.
In preparation to fix ext4_iget() to set 'ext4_dax_aops' for ext4 DAX files, add ext4_bmap() to 'ext4_dax_aops'. .bmap works for DAX inodes. [1]
