Hmm, I just noticed there is actually a hash-ptr option for trace ring
buffer:

  hash-ptr
        When set, "%p" in the event printk format displays the
        hashed pointer value instead of real address.
        This will be useful if you want to find out which hashed
        value is corresponding to the real value in trace log.

I am glad people noticed the usefulness of real addresses in tracepoint
before I did.

I will backport this to our 5.10 kernel.

Thanks.
