The reason for separating functions in this case wasn't that the separate function
would be called several times. It was to improve code readability. If anything,
I would argue that it might sense to split the already lengthy probe function
further instead of combining it.

Maybe I am old fashioned. Maybe the old "split your code into multiple functions
if the function size is larger than X lines" no longer applies, and it is now
"never split functions unless the separated function is called more than once".
Still, I am quite concerned that accepting this patch would result in a flurry
of similar patches which would all do nothing but hurt readability, using the
same set of arguments. I really don't like where this is going. I am going to
leave it up to Wim to decide if and how to proceed.
