From 4bdc8606e6fcd3b243e7ceeddd78e8d9a699a63e Mon Sep 17 00:00:00 2001 From: Viktor Mihajlovski Date: Fri, 5 Oct 2012 15:59:08 +0200 Subject: [PATCH] S390: Buffer too small for large CPU numbers. The output buffer for virFileReadAll was too small for systems with more than 30 CPUs which leads to a log entry and incorrect behavior. The new size will be sufficient for the current architectural limits.
