Re: [PATCH v2 0/2] [RFC] virtio-rng entropy leak reporting feature

Hi Jason,

I really didn't mean to interrupt your holidays.

I posted this as an RFC exactly because I don't want this to be merged _as is_, it's just a trigger for discussion.
It is v2 just as a response to Michael's comments in the previous version and fixes for the CI.

Also, there are other people that expressed interest in this and they wanted to participate in the coversation, so that's just
that.

I hope you enjoy your vacation, get some rest and speak to you once you' re back :)

Cheers,
Babis

You sent a v2, but I'm not back until the 11th to provide comments on
v1. I still think this isn't the right direction, as this needs tie-ins
to the rng to actually be useful. Please stop posting new versions of
this for now, so that somebody doesn't accidentally merge it; that'd be
a big mistake. I'll paste what I wrote you prior:

| Hi Babis,

| But as a cursory look, I'm happy that you've written the hardware-side

| itself, similar to how vmgenid works.
|
| When I'm back in a few weeks, I'll see if I can either write a
| description of what I have in mind, or simply integrate the useful
| hardware work here into an expanded patch series.

| [Please don't merge anything for now.]

So: you wrote some maybe useful hardware code. The rest is wrong. And we
haven't even concluded discussions on whether the virtio interface is
the right one. In fact, I had previously asked if we could schedule this
all until March. Marco from your team then sent an impatient email, so I
said, alright, what about Feb 11 when I'm back. That's annoying for me
but I figured I'd just shuffle everything around and prioritize this.
Then, instead of waiting for that, you posted v1 of this patchset the
next day. I asked you again. And now, while I'm away on the first
holiday in a while with very little connectivity and no laptop, you post
a v2. So I'm really annoyed. In order to avoid all doubt about this, let
me then just NACK this, and I'll lift the nack when I'm back:
