  * DM_TARGET_MSG:
  * Pass a message string to the target at a specific offset of a device.
- *
- * DM_DEV_SET_GEOMETRY:
- * Set the geometry of a device by passing in a string in this format:
- *
- * "cylinders heads sectors_per_track start_sector"
- *
- * Beware that CHS geometry is nearly obsolete and only provided
- * for compatibility with dm devices that can be booted by a PC
- * BIOS.  See struct hd_geometry for range limits.  Also note that
- * the geometry is erased if the device size changes.
