%description
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 "/proc/<pid>/ksm" interface, which is available in
pf-kernel (https://gitlab.com/post-factum/pf-kernel/).
