From f1f3afd59d78db163f6655394980290c1bdf9eab Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Fri, 9 Sep 2022 20:29:01 +0000 Subject: [PATCH] Docs/admin-guide/mm/damon/usage: note DAMON debugfs interface deprecation plan Commit b18402726bd1 ("Docs/admin-guide/mm/damon/usage: document DAMON sysfs interface") announced the DAMON debugfs interface deprecation plan, but it is not so aggressively announced. As the deprecation time is coming, this commit makes the announce more easy to be found by adding the note at the beginning of the DAMON debugfs interface usage document.
