Subject: [PATCH 4.14 26/35] perf tests attr: Fix group stat tests

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Olsa <jolsa@...hat.com>

commit f6a9820d572bd8384d982357cbad214b3a6c04bb upstream.

We started to use group read whenever it's possible:

  82bf311e15d2 perf stat: Use group read for event groups

That breaks some of attr tests, this change adds the new possible
read_format value.
