%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 pmadv_ksm() syscall, which is available in linux-cachyos-bore/linux-cachyos-bore-lto kernels.
