Thats the idea. The 'hugetlb zone' will only be usable for allocations
which are guaranteed reclaimable. Reclaimable includes userspace
usage (since at worst an in use userspace page can be swapped out then
paged back into another physical location).
For your sort of mixed use this should be a fine solution. However
there are mixed use cases that that this will not solve, for example
if the system usage is split between HPC uses and kernel allocation
heavy workloads (say forking 10quintillion java processes) then the
hugetlb zone will need to be made small to keep the kernel allocation
heavy workload happy.
