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.
