From dda5500853c736aca9ad8c14f7d22cd9d9f9fb36 Mon Sep 17 00:00:00 2001 From: LOLi Date: Fri, 21 Sep 2018 18:42:42 +0200 Subject: [PATCH] vdev_disk_error() prints ASCII SOH to debug log Currently vdev_disk_error() prepends its messages sent to the internal ZFS debug log with KERN_WARNING, which is currently defined as follows: #define KERN_SOH "\001" #define KERN_WARNING KERN_SOH "4" Since "\001" (ASCII Start Of Header) is not printable this results in weird characters displayed when inspecting the debug log. This commit simply removes this superfluous prefix passed to zfs_dbgmsg().
