From 333e4d79316c9ed5877d7aac8b8ed22efc74e96d Mon Sep 17 00:00:00 2001 From: Maor Gottlieb Date: Mon, 16 Jun 2025 11:26:21 +0300 Subject: [PATCH] RDMA/core: Rate limit GID cache warning messages The GID cache warning messages can flood the kernel log when there are multiple failed attempts to add GIDs. This can happen when creating many virtual interfaces without having enough space for their GIDs in the GID table. Change pr_warn to pr_warn_ratelimited to prevent log flooding while still maintaining visibility of the issue.
