└─>Build DAMON-based reclaim (DAMON_RECLAIM)
In linux kernel since version 5.2 (release Date: 2019-07-07)  
This builds the DAMON-based reclamation subsystem. It finds pages
that not accessed for a long time (cold) using DAMON and reclaim

This is suggested to be used as a proactive and lightweight
reclamation under light memory pressure, while the traditional page
scanning-based reclamation is used for heavy pressure.
