From: Dave Chinner <dchinner@xxxxxxxxxx> Only regular files can use DAX for data operations, so we should restrict setting it on the VFS inode to regular files. Setting it on metadata inodes may cause the VFS to do the wrong thing for such inodes, so avoid potential problems by restricting the scope of the flag to what we know is supported.
