Its filename was mm-damon-core-add-damos-quota-gaol-metric-for-per-memcg-per-numa-free-memory.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: add DAMOS quota gaol metric for per-memcg per-numa free memory Date: Fri, 17 Oct 2025 14:26:58 -0700 Add a variant of DAMOS_QUOTA_NODE_MEMCG_USED_BP, for the free memory portion. The value of the metric is implemented as the entire memory of the given NUMA node subtracted by the given cgroup's usage. So from a perspective, "unused" could be a better term than "free". But arguably it is not very clear what is better, so use the term "free".
