From 00fd2cb0ec4208a32272b4c2f1063ab99a76473c Mon Sep 17 00:00:00 2001 From: Peter Oberparleiter <oberpar@linux.vnet.ibm.com> Date: Thu, 2 Jul 2015 09:06:55 +0200 Subject: [PATCH] s390/sclp: Change SCLP console default buffer-full behavior Dropping kernel messages during a console-buffer-full condition is preferable to halting the system until console messages are delivered, especially for production systems. Update default for sclp_console_drop kernel parameter accordingly.
