If the early refactoring requires changes - yeah, you get that done, signed off and committed (while possibly doing higher level design review of later patches that might be applicable regardless of the early refactoring - like if you decide to rename a newly created function in an early patch, that shouldn't hurt the review going on in later patches, for instance) & update later patches with the knock-on effects. No need to start new mail threads/lose review context/etc.

On Git, I normally would have done that on separate, but related,
branches and pull requests. II find it much easier to work with
rebases and cherry-picks across branches than on the same branch. A
rebase -i can turn dreadful if the same part of the code is touched by
more than one patch, and it can be almost impossible if that pattern
happens more than once.

In my use of the term, a patch series is a mandated order of directly
related commits, like you would have in a branch, if the patches are
logically separated into clear individual steps, for the clarity of
review.

Perhaps the name clash has caused more trouble than the original
discussion. If that's not what most people would have thought,
apologies for the confusion.
