Description

Userspace KSM helper daemon.

The daemon goes through the list of userspace tasks (once per 5 seconds) and hints them to apply MADV_MERGEABLE to anonymous mappings for ksmd kthread to merge memory pages with the same content. Only long-living tasks are hinted (those that were launched more than 10 seconds ago).

This requires pmadv_ksm() syscall, which is available in pf-kernel.

Configuration

The daemon requires zero configuration.
