If anyone has any objections, please let me know. ------------------ From: Toshi Kani commit 94dbb63117e82253c9592816aa4465f0a9c94850 upstream. 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', since bmap works for DAX inodes.
