-/*
- * A traditional ioctl interface for the device mapper.
- *
- * Each device can have two tables associated with it, an
- * 'active' table which is the one currently used by io passing
- * through the device, and an 'inactive' one which is a table
- * that is being prepared as a replacement for the 'active' one.
- *
- * DM_VERSION:
- * Just get the version information for the ioctl interface.
- *
- * DM_REMOVE_ALL:
- * Remove all dm devices, destroy all tables.  Only really used
- * for debug.
- *
- * DM_LIST_DEVICES:
- * Get a list of all the dm device names.
- *
- * DM_DEV_CREATE:
- * Create a new device, neither the 'active' or 'inactive' table
- * slots will be filled.  The device will be in suspended state
- * after creation, however any io to the device will get errored
- * since it will be out-of-bounds.
- *
- * DM_DEV_REMOVE:
- * Remove a device, destroy any tables.
- *
- * DM_DEV_RENAME:
- * Rename a device or set its uuid if none was previously supplied.
- *
- * DM_SUSPEND:
- * This performs both suspend and resume, depending which flag is
- * passed in.
- * Suspend: This command will not return until all pending io to
- * the device has completed.  Further io will be deferred until
- * the device is resumed.
- * Resume: It is no longer an error to issue this command on an
- * unsuspended device.  If a table is present in the 'inactive'
- * slot, it will be moved to the active slot, then the old table
- * from the active slot will be _destroyed_.  Finally the device
- * is resumed.
- *
- * DM_DEV_STATUS:
- * Retrieves the status for the table in the 'active' slot.
- *
- * DM_DEV_WAIT:
- * Wait for a significant event to occur to the device.  This
- * could either be caused by an event triggered by one of the
- * targets of the table in the 'active' slot, or a table change.
- *
- * DM_TABLE_LOAD:
- * Load a table into the 'inactive' slot for the device.  The
- * device does _not_ need to be suspended prior to this command.
- *
- * DM_TABLE_CLEAR:
- * Destroy any table in the 'inactive' slot (ie. abort).
- *
- * DM_TABLE_DEPS:
- * Return a set of device dependencies for the 'active' table.
- *
- * DM_TABLE_STATUS:
- * Return the targets status for the 'active' table.
- *
- * 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.

- * All ioctl arguments consist of a single chunk of memory, with
