Its filename was mm-damon-core-fix-a-comment-about-damon_set_attrs-call-timings.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: SeongJae Park 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.
