But it is hard to discuss anything without patches so we can continue

super-pressing so it can go ontop of the SNP pile.

Yah, it's all theoretical at this point. Didn't mean to derail things
though. I mainly brought it up to suggest that Venu's original approach of
returning the encryption bit via a pointer argument might make it easier to
expand it for other purposes in the future, and that naming it for that
future purpose might encourage future developers to focus their efforts
there instead of potentially re-introducing duplicate code.

But either way it's simple enough to rework things when we actually
cross that bridge. So totally fine with saving all of this as a future
follow-up, or picking up either of Venu's patches for now if you'd still
prefer.

So, what is the consensus? Do you want me to submit a patch after the
SNP changes go upstream? Or, do you want to roll in one of the patches
that I posted earlier?


Will incorporate your changes in v9. And will see what others say about it.


Now that I am incorporating the feedback in my wip branch, at this time I am dropping your cleanup mainly because some of recommendation may require more rework down the line; you can submit your recommendation as cleanup after the patches are in. I hope this is okay with you.

thanks
