Subject: [PATCH 6/8] perf scripts python: Add Python 3 support to sched-migration.py
Date:   Tue, 8 May 2018 21:27:47 +0000
Message-ID: <0100016341a737a5-44ec436f-3440-4cac-a03f-ddfa589bf308-000000@email.amazonses.com>

References: <cover.1525811971.git.jeremy@jcline.org>
Feedback-ID: 1.us-east-1.z18Isoc/FaoPOvCyJyi1mnTt8STwoRuibXVNoUcvG6g=:AmazonSES
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Support both Python 2 and Python 3 in the sched-migration.py script.
This should have no functional change.
