From 2fcbbaff921492469dc7b1c4e2bb3dd8b5dc7c1d Mon Sep 17 00:00:00 2001 From: Youssef Samir Date: Sun, 2 Aug 2026 23:33:52 +0200 Subject: [PATCH] net: qrtr: ns: Raise node count limit to 512 [ Upstream commit ff194cffd586cbd4cc49eccb002c65f2a902a277 ] The current node limit of 64 breaks the functionality for a number of AI200 deployments that have up to 384 nodes. Raise the limit to 512. Also, the backport of commit 27d5e84e810b ("net: qrtr: ns: Limit the total number of nodes") to 5.10, 5.15 and 6.1 dropped the node_count-- hunk in ctrl_cmd_bye(). Add it back.
