From 2e3a96810a37c0e58e9c59a5ef7439968a410c70 Mon Sep 17 00:00:00 2001 From: Joe Jin Date: Wed, 14 Mar 2018 10:14:03 -0700 Subject: [PATCH] xenbaked.c: Avoid divide by zero issue xenbaked.c -> dump_stats(), run_time = time(&end_time) - time(&start_time), time() returns the value in seconds. If one cancels xenmon.py immediately after started, run_time can be zero, and then xenbaked will hit divide by zero fault.
