| Date: Fri, 9 Sep 2022 20:29:01 +0000 |

| 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. |

| DAMON exports eight files, ``attrs``, ``target_ids``, ``init_regions``, |
| ``schemes``, ``monitor_on``, ``kdamond_pid``, ``mk_contexts`` and |
| ``rm_contexts`` under its debugfs directory, ``<debugfs>/damon/``. |
