From fa48beb5f485a82a15f777198c770feb6d01c794 Mon Sep 17 00:00:00 2001 From: SeongJae Park Date: Fri, 3 Nov 2017 19:17:27 +0900 Subject: rcutorture: Simplify logging Both the 'kvm.sh' and 'kvm-test-1-run.sh' scripts log messages by printing the message to 'stdout' and then also printing it into the log file. Generation of the message thus occurs twice, once for 'stdout' and once for the log file. Moreover, many of the messages contain 'date' output, which results in date being invoked twice (once for stdout print, once for log file write). As a result, the date information in stdout and log file can differ, which could cause confusion. This commit therefore simplifies the logging procedure by using 'tee'.
