Hi Andrii.
I noticed you add tools/testing/selftests/bpf/progs/test_btf_*, so drop
this problem to you.
I failed to run bpf: test_btf on debian9(stretch), hope you can give me
some suggestion.
Testing env: "Debian GNU/Linux 9 (stretch)"
kernel: 5.7.0-rc2 5.6 both failed
Description: run bpf: test_btf failed with ""Arg#0 type PTR in
test_long_fname_2() is not supported yet.""
Whole run log and kconfig please see the attatchment.
