Overview

This module disables Transparent Hugepages (THP) on Linux platforms as required by applications such as MongoDB and Redis. The procedure is based on recommendations published at mongodb.org.

The module changes the /sys/kernel/mm/transparent_hugepage/enabled and /sys/kernel/mm/transparent_hugepage/defrag settings, adds an init service to ensure the changes persist across reboots, and if applicable, configures tuned.
