From 86ae64cde2f7165a20e2824431cec8e820a0b689 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Thu, 7 Sep 2023 02:29:24 +0000 Subject: Docs/mm/damon/design: add a section for kdamond and DAMON context The design document is not explaining about the concept of kdamond and the DAMON context, while usage document does. Those concept explanation should be in the design document, and usage document should link those. Add a section for those.
