DAMON is a framework that allows user space
to influence and control the kernel’s memory-management operations. It
first entered the kernel with the 5.15 release, and has been gaining
capabilities ever since. At the 2023 Linux Storage, Filesystem,
Memory-Management and BPF Summit, DAMON author Seongjae Park provided
an overview of the current status of DAMON development and where it can be
expected to go in the near future.
