Sorry for the delay. I just tried applying this to my tree, but got the
following build warnings, and then errors:

Note, I'm using gcc 7.1.1, which might be what is showing the build warnings,
but that doesn't explain the build errors.
So obviously, I can't take this as is :(

Looks like the second __entry->size, probably needs a type cast.
Would something like:
__entry->size,
(int)__entry->size, &__entry->data
work?
I haven't looked at the others, but I'm guessing they are probably
similar issues.

Hi Greg,
Was missing a few export symbols for module mode... Sorry about that.
Will correct the trace warnings as well and get v8 sent out ASAP.
Thanks for the input.
