Is this email defunct now, that you add second SoB?

I still see in this patchset around 5 different subsystems. Nothing in
the cover letter explains the dependencies, so grouping looks like
coincidence and you just make it difficult for maintainers for no
reason.
Please organize your patchsets per subsystems, see submitting patches
doc for more details.
Best regards,
