Returns Optional. Transparent hugepage support for anonymous memory can be entirely disabled (mostly for debugging purposes) or only enabled inside MADV_HUGEPAGE regions (to avoid the risk of consuming more memory resources) or enabled system wide.

See https://docs.kernel.org/admin-guide/mm/transhuge.html for more details.
