Its filename was mm-damon-core-use-damon_nr_samples_per_aggr-for-max-merge-threshold.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: SJ Park Subject: mm/damon/core: use damon_nr_samples_per_aggr() for max merge threshold Date: Tue, 1 Sep 2026 22:47:34 -0700 Patch series "mm/damon: cleanup code, add test cases, and update guidances in docs". Misc cleanup, improvements and updates of code, test, and documents. Patches 1-5 cleanup DAMON code. Patches 6-10 adds kunit and selftest test cases for recently fixed bugs and a new feature. Patches 11 and 12 update guidelines for AI review and what document to read, on DAMON documents. This patch (of 12): kdamond_merge_regions() open-codes max region merge threshold calculation. What it does is fundamentally the same as damon_nr_samples_per_aggr() but missing a few corner cases. The unhandled corner cases should be rare and make only a negligible level of monitoring results degradation. But having the inconsistency could increase future maintenance burden. Use the dedicated function.
