The commit message now describes the actual mechanism correctly,
thanks for reworking it:

One process note, though: please don't repost new versions this
quickly. v2 followed the review comments almost immediately, which
means other reviewers who were still looking at v1 never got a
chance to chime in before the thread moved on, and the discussion
gets fragmented across versions.

Documentation/process/submitting-patches.rst ("Don't get
discouraged - or impatient") asks submitters to wait a minimum of
one week before reposting; the same courtesy applies to new
versions while review is still ongoing. Collecting all the feedback
on one version and then sending a single respin saves everyone
time.
