I don't want to devalue internal review, it's good stuff for the most part. However, there are a few issues. Most patches have seen a bunch of rebases and fixups since the review. Sometimes the review means, good enough for merging internally. And finally, I don't want us to give the impression of internal rubber stamp review. Basically I want every internal Reviewed-by confirmed on the public list. I think this pretty much aligns with what Paulo said in the cover letter. It's a matter of taste whether you require the confirmation of reviews or change them to Cc's and ask for the same. For the changelogs, I agree we should start scrubbing them for v1 posted on the public list.

Let's only merge what we are confident that review is still valid or ask for re-reviews and extra acks. One idea that I heard this morning was to use on internal some custom tag like "Internally-Reviewed-by:" but I don't like this idea of adding custom tags and I trust our commiters to differentiate between valid internal reviews and risky ones. Agree? Thoughts? I've been all favour of converting R-b's to Cc:s and embedding any meaningful changelog entries into the commit text. Because it'll be the first revision sent to public, you can't trace any of the previous review comments back by searching mailing lists. It'll only add confusion. I don't see the value added by leaving just the changelog entries to the commit messages. Quite contrary, they are a potentialcause of confusion when somebody tries to track down non-existent review history in public. And sending pre-reviewed patches to community mailing lists also doesn't feel quite right. Even for IRC review the BKM is to respond to the mailing list and note that the patch received a R-b in IRC, for documentation purposes. And when you add the fact that there is high chance of not invalidating the reviews when they should be (due to the urgency and amount of patches there's related to new product development), I see it more as a problem maker than a solver. It has little to give but the trade has much to lose. I agree with some points but also think it is not desirable to just lose any record of potentially significant review effort that went in before first public posting. The only idea I can think of at the moment, if we don't want to use a separate tag, is to, as you say, squash meaningful change log entries into the commit, convert the r-b to r-b # internal (similar to r-b # v1 notation), and add the reviewer as cc explicitly: drm/i915: Some patch title Some commit text. Signed-of-by: A Reviewed-by: B # internal Cc: B B then follows up with upgrading the r-b. ?

Because it'll be the first revision sent to public, you can't trace any of the previous review comments back by searching mailing lists. It'll only add confusion. I don't see the value added by leaving just the changelog entries to the commit messages. Quite contrary, they are a potentialcause of confusion when somebody tries to track down non-existent review history in public.
