sjA number of DAMON changes for Linux 6.19-rc1 has merged into the mainline as a part of MM subsystem pull request [1]. I again recommend people to read Andrew's great summary of the important changes on MM subsystem.
Among the DAMON changes, below four specially come to me. I hope the first change to help my ex-colleagues, and appreciate to Quanmin and Bijan for their continued DAMON works. Fourth one is only for celebrating my Camino challenge completion;)
1. Per-memcg per-node memory usage based DAMOS auto-tuning [2]. This allows cgroup-level NUMA memory management, such as hot pages promotion, cold pages demotion and reclaim. This was developed as a collaboration with my now-ex-colleagues at Meta.
2. Address alignment fix for DAMON modules [3]. This was developed as a followup fix of ARM32 LAPE support, by Quanmin from Huawei.
3. Pin-point targets removal [4]. This was developed as a collaboration [5] with Bijan, as a followup of his vaddr-based DAMOS-migration to multi-destination nodes.
4. Kunit tests for online parameters commit [6]. I started working on this on the Camino de Santiago[7]. It has delayed much longer than I expected, but I finally made it.
