The dax_layout_busy_page() and dax_layout_busy_page_range() helpers were originally exposed so filesystems could find pinned DAX pages before changing file layouts. Filesystem callers now use dax_break_layout(), which provides the complete operation, leaving no direct users of these lookup helpers outside fs/dax.c.
Remove the unused whole-mapping wrapper and make the remaining range helper private to fs/dax.c. This reduces the exported DAX interface with no functional change.
