*
* 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.
*
* 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.
