Description: lfsck built against 1.4.x cannot run against 1.6.0 lustre
Details    : the definition for OBD_IOC_GETNAME changed in 1.6.0.  One of the
	     few external users of this ioctl number is lfsck's call to
	     llapi_lov_get_uuids() and this caused lfsck to fail at startup.
	     Add the old ioctl number to the handler so both old and new
	     lfsck can work.
