Subject: [PATCH 01/15] perf script python: add Python3 support to netdev-times.py
Date: Fri, 22 Feb 2019 15:06:05 -0800 [thread overview]
Message-ID: <20190222230619.17887-2-tonyj@suse.de> (raw)
In-Reply-To: <20190222230619.17887-1-tonyj@suse.de>
Support both Python2 and Python3 in the netdev-times.py script
There may be differences in the ordering of output lines due to
differences in dictionary ordering etc. However the format within lines
should be unchanged.
The use of 'from __future__' implies the minimum supported Python2 version
is now v2.6
