That's true, the user space must be able to interpret the object identifier. So if we extend the command to add more identifiers we will have to add the bitmask to the dump request, and have the user space tell the kernel which objects it can recognize. I was just saying that we don't have to add such attribute now, maybe leave a comment in a strategic place for our future selves?
