Subject: [PATCH 04/15] perf script python: add Python3 support to failed-syscalls-by-pid.py
Date: Fri, 22 Feb 2019 15:06:08 -0800
Message-ID: <20190222230619.17887-5-tonyj@suse.de> (raw)
In-Reply-To: <20190222230619.17887-1-tonyj@suse.de>

Support both Python2 and Python3 in the failed-syscalls-by-pid.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
