then please divide this into smaller commits. Cosmetic changes
should be in separate patches, and functional changes in
different commits. They should not be mixed together.

I am actually asking about the reverse. Are we confident that
patches 1, 2, and 3 function correctly without this one? I didn't
notice any dependencies.

If that's the case, I would suggest removing this patch from the
series, merging patches 1, 2, and 3, and then addressing this
patch separately. It can be properly divided and expanded into a
more comprehensive series.
