From 2ccb34d882b01305794e7780b6dd691179ddae7e Mon Sep 17 00:00:00 2001 From: Denis Kondratenko Date: Fri, 10 Feb 2012 12:54:45 +0200 Subject: [PATCH] LU-958 tests: debug_mb set incorrectly for smp or vm For cpus with number of cores or for some VMs, number of possible CPUs in the system could be greater than number of cpu reported by getconf. Added check for maximum debug buffer size.
