perf script python: Add Python3 support to failed-syscalls-by-pid.py
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 Signed-off-by: Tony Jones <tonyj@suse.de> Cc: Tom Zanussi <tzanussi@gmail.com> Link: http://lkml.kernel.org/r/20190222230619.17887-5-tonyj@suse.de Signed-off-by: Seeteena Thoufeek <s1seetee@linux.vnet.ibm.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
