From 36d6b929bb0c7cc1cc742d9b5805537d3b651094 Mon Sep 17 00:00:00 2001 From: Kenny Glowner Date: Thu, 21 May 2026 11:14:05 -0500 Subject: [PATCH] rust: module_param: add missing newline to pr_warn_once Add a trailing newline ('\n') to the pr_warn_once! call in set_param to ensure the kernel ring buffer flushes the message correctly and prevents log line smearing.
