From 4c8cc55b3c0ebe989e727017933945b68b4327cd Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 1 Jun 2011 23:22:30 -0400 Subject: ktest: Fix off-by-one in config bisect result Because in perl the array size returned by $#arr, is the last index and not the actually size of the array, we end the config bisect early, thinking there is only one config left when there are in fact two. Thus the result has a 50% chance of picking the correct config that caused the problem.

This is because a ';' is used between the two commands and if the second command fails, only the first command's return code is returned. Using a '&&' between the two commands fixes this.
