[PATCH 07/11] Docs/admin-guide/mm/damon/usage: link design doc for details of kdamond and context

From: SeongJae Park
Date: Wed Sep 06 2023 - 22:29:53 EST


The explanation of kdamond and context is duplicated in the design and
the usage documents. Replace that in the usage with links to those in
the design document.
