Const ExperimentalHugepages for which a commitment to allocate has been made, but no allocation has yet been made.
This is reported as a separate metric rather than a usage state because reserved pages are already counted in free pages.
They represent a subset of free pages that cannot be used for non-reserved allocations.
This metric is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
Number of reserved hugepages.
