Subject: [PATCH] selftests/bpf: Fix check in global_data_init.
Date: Thu,  3 Sep 2020 11:01:21 -0700	[thread overview]
Message-ID: <20200903180121.662887-1-haoluo@google.com> (raw)

The returned value of bpf_object__open_file() should be checked with
IS_ERR() rather than NULL. This fix makes test_progs not crash when
test_global_data.o is not present.
