In this case it probably doesn't matter much, because there is a key
difference between this and most other patchsets of this type: there is
an order that this can be done which is safe.  Specifically, add the
#include where it needs to go as a patch series, and then remove it from
the build.  If this is merged into a git tree and the resulting build
fails, it will be obvious what needs to happen, and sfr and Linus are
really good about managing that in linux-next and mainline,
respectively, so I don't even think we need to go to this "special
procedure" for this case.
