max_huge_pages looks OK, maybe it has a bad name. Because that is
a variable used to pass desired hugetlb pool size by sys admin. It
is used only in the reservation path. Kernel pretty much needs at
least two variables: what is the desired target and what is current
reservation state (that tracked by nr_huge_pages).
