Hi! Thank you for your work on the subject, I think it's a really useful feature. I've reviewed your patch and I have a few questions.
First of all, have you thought about creating a gun parameter to display memory scheduling information? I agree that this is an important feature, but I think only for debugging.
Secondly, I noticed that for the child_rinfo_hash key you use a counter (int) and can it lead to collisions? Why didn't you generate a hash from childRestrictInfo for this? For example, something like how it is formed here [0].
