Date: Wed, 14 Aug 2019 09:47:41 -0700
From: Stanislav Fomichev <sdf@...gle.com>

Subject: [PATCH bpf-next 3/4] selftests/bpf: test_progs: remove global
fail/success counts
Now that we have a global per-test/per-environment state, there
is no longer the need to have global fail/success counters
(and there is no need to save/get the diff before/after the
test).
