From f74288cf94d73f58a338fc58d8e2907673bb36e5 Mon Sep 17 00:00:00 2001 From: Haren Myneni Date: Mon, 9 Feb 2026 22:18:58 -0800 Subject: [PATCH 01/11] drmgr: Update cpuless_lmb_count NUMA counter during LMB removal Upstream: merged, expected in v1.3.15 Git-commit: f74288cf94d73f58a338fc58d8e2907673bb36e5 After removing LMBs from a NUMA node, LMB counters should be decremented. In the case of CPU less node, cpuless_lmb_count should be decremented. But the current code reduces cpuless_node_count instead of cpuless_lmb_count. This patch reduces cpuless_lmb_count NUMA counter based on number of LMBs selected from that specific CPU less NUMA node.
