From 2cef5b4472c602e6c5a119aca869d9d4050586f3 Mon Sep 17 00:00:00 2001 From: Nicolas Bouchinet Date: Mon, 24 Feb 2025 10:58:19 +0100 Subject: scsi: logging: Fix scsi_logging_level bounds Bound scsi_logging_level sysctl writings between SYSCTL_ZERO and SYSCTL_INT_MAX. The proc_handler has thus been updated to proc_dointvec_minmax.
