From 5af28560fe4f091c215580b16672004fdf08f304 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Mon, 29 Jan 2024 17:35:40 -0800 Subject: Docs/admin-guide/mm/damon/usage: use sysfs interface for tracepoints example Patch series "mm/damon: make DAMON debugfs interface deprecation unignorable". DAMON debugfs interface is deprecated in February 2023, by commit 5445fcbc4cda ("Docs/admin-guide/mm/damon/usage: add DAMON debugfs interface deprecation notice"). Make the fact unable to be easily ignored by removing an example usage from the document (patch 1), renaming the config (patch 2), adding a deprecation notice file to the debugfs directory (patches 3-5), and renaming the debugfs file that essnetial to be used for real use of DAMON (patches 6-9). This patch (of 9): DAMON tracepoints example on the DAMON usage document is using DAMON debugfs interface, which is deprecated. Use its alternative, DAMON sysfs interface.
