I just saw your reply to v1 thread.  General advice would be slow down a bit.
Even if you have reviews, a new patch set should sit for at least a few days
to gather multiple reviews before a revision.

For this sort of change I'd expect two patches.
1. Sort headers as is, not changes.
2. Add and remove headers.

Both are good to do, but if you do them together as you had in v1
it is annoyingly hard to review.

Even if you don't sort, these should be inserted as near
as possible to where they'd end up in a sorted list.
