    SubjectRe: bpf selftest failed in 5.4.210 kernel
    Sorry for the confusion, results are indeed confusing to me .
    If I try with git bisect I get

    git bisect bad
    9d6f67365d9cdb389fbdac2bb5b00e59e345930e is the first bad commit

    If I try to test myself with multiple test scenarios(I have mentioned
    in the previous mails) for the bad commits , I see that bad commits
    are
    bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds()
    selftests/bpf: Fix test_align verifier log patterns
    selftests/bpf: Fix "dubious pointer arithmetic" test

    Thanks,
    Rajesh Dasari.
