Not a comment on the patches themselves, just a workflow suggestion for
*future* postings: please enable shallow threading in git.

git config sendemail.thread       true
git config sendemail.chainreplyto false

Thanks

Hello Eric,

After looking into the series, I found that patches 2/3 & 3/3 are actually
addressing issues introduced by the 1/3 patch. It looks to me that these
3 patches should be squashed into 1 commit, since they all focus on adding
a feature for ESRT to support multiple controllers.

However, originally, the 3 separate commits come from the edk2-staging
repository, so I am not very sure what approach should be adopted when
merging them back to the edk2 repo master branch.

(Includes the stewards here for suggestions.)

My personal preference is to merge them together as one patch.

Best Regards,
Hao Wu

[Eric Jin]

Hao,

Thank you for the suggestion. I have sent the patch v2 out and merge series to one patch.
Let's wait one day to follow the possible comments from stewards. Thanks.

Best Regards
Eric

Sorry about the late response.

I certainly agree that a single patch series should avoid introducing a
bug or esp. regression, just for another patch in the same series to fix
it up. In that case, both halves indeed belong to a single patch.

However, speaking generally (not knowing any specifics here), that
doesn't mean that everything should be squashed into a single patch. The
series (speaking generally) should still have a fine-grained structure;
each patch should do as little, and as well isolated, as reasonably
possible.

Thanks
Laszlo
