Subject: mm/damon/Kconfig: add DAMON debugfs interface deprecation notice
Date: Thu, 9 Feb 2023 19:20:08 +0000
DAMON debugfs interface has announced to be deprecated after >v5.15 LTS
kernel is released. And, v6.1.y has announced to be an LTS[1].
Though the announcement was there for a while, some people might not
noticed that so far. Also, some users could depend on it and have
problems at movng to the alternative (DAMON sysfs interface).
For such cases, note DAMON debugfs interface as deprecated, and contacts
to ask helps on the Kconfig.
