If this helps break the tie:

dsa@kenny:~/kernel.git$ /tmp/perf/perf test 29
29: Test cumulation of child hist entries                    : Ok

dsa@kenny:~/kernel.git$ /tmp/perf/perf --version
perf version 4.7.rc5.g02184c

But running on net-next kernel from a few days ago + 1 local patch:
dsa@kenny:~/kernel.git$ uname -r
4.7.0-rc2-00862-g23854048c919

(I do get a few other failures)
