Subject: mm/damon/core: fix a comment about damon_set_attrs() call timings
Date: Thu, 7 Sep 2023 02:29:26 +0000
The comment on damon_set_attrs() says it should not be called while the
kdamond is running, but now some DAMON modules like sysfs interface and
DAMON_RECLAIM call it from after_aggregation() and/or
after_wmarks_check() callbacks for online tuning. Update the comment.
