However, this is an 'opt in' feature.  So, I would not expect anyone who
carefully plans the size of their hugetlb pool to enable such a feature.
If there is a use case where hugetlb pages are used in a non-essential
application, this might be of use.

I would really like to hear about the specific usecase. Because it
smells more like a misconfiguration. What would be non-essential hugetlb
pages? This is not a resource to be pre-allocated just in case, right?
