I can see in the kernel code that an error is returned if the message

to get it in the libmount code.

That's not really a communication protocol problem.

Still I need to work out how to detect it, maybe it is seen by
the code in libmount already and I simply can't see what I need
to do to recognise it ...

So I'm stuck wanting to verify I have got everything that was
sent and am having trouble moving on from that.
This is the commit that should add the overrun detection capability:
