What other code does is irrelevant. I'm trying to maintain and
improve the consistency of the format used for the fs/iomap code.

5 functions that have that format, compared to 45 that do have the
formatting I asked you to retain. It think it's pretty clear which
way consistency lies here...

Inconsistency always occurs when multiple people modify the same
code. Often that's simply because reviewers haven't noticed the
inconsistency - it's certainly not intentional.
Saying "No, I'm going to make the code less consistent because it's
already slightly inconsistent" is, IMO, not a valid response to a
review request to conform to the existing code layout in that file,
especially if it improves the consistency of the code being
modified. That's really not negotiable....
Cheers,
Dave.
