    bpf: Remove struct bpf_verifier_env argument from print_bpf_insn · abe08840
    Jiri Olsa authored
    We use print_bpf_insn in user space (bpftool and soon perf),
    so it'd be nice to keep it generic and strip it off the kernel
    struct bpf_verifier_env argument.
    This argument can be safely removed, because its users can
    use the struct bpf_insn_cbs::private_data to pass it.
    By changing the argument type  we can no longer have clean
    'verbose' alias to 'bpf_verifier_log_write' in verifier.c.
    Instead  we're adding the  'verbose' cb_print callback and
    removing the alias.
    This way we have new cb_print callback in place, and all
    the 'verbose(env, ...) calls in verifier.c will cleanly
    cast to 'verbose(void *, ...)' so no other change is
