The interesting split is between material that I will use to build my
"cleanup" series on the one hand and the "dt" series on the other hand.
With an order of submission upstream that is always "cleanup" before "dt".

That said, you can imagine that it's always preferable to have a
separation between source and dt.

Concerning the number of patches, as long as it is not excessive, I tend
to pay little attention to that.
