Hi Mat, we had checked test status on v5.7-rc1, which has the below failures

  "kernel-selftests.bpf.test_progs.fail": [
  "kernel-selftests.bpf.test_align.fail": [
  "kernel-selftests.bpf.test_tcpbpf_user.fail": [	<=3D=3D new in v5.7-rc1
  "kernel-selftests.bpf.test_btf.fail": [
  "kernel-selftests.bpf.test_sysctl.fail": [
  "kernel-selftests.bpf.test_progs-no_alu32.fail": [
  "kernel-selftests.bpf.test_bpftool.sh.fail": [
  "kernel-selftests.bpf.test_tc_edt.sh.pass"		<=3D=3D pass in v5.7-rc1

v5.7-rc1 had extra "kernel-selftests.bpf.test_tcpbpf_user.fail", but with
kernel-selftests.bpf.test_tc_edt.sh.pass, which failed in 531346f5a4531c he=
re.

We haven't root caused them yet, will plan some effort to see whether the t=
est
is stable and try to resolve other failure if it is env issue.

Thanks
