Confused.

See, my problem is that normally I will hold off on sending a patch to
its subsystem maintainer until its prerequisite patch(es) are in mainline.
But for each of these patches, I don't know what the exact prerequisites
are.  Help?

(The simple alternative is for me to seek acks and merge them all
myself.  But sometimes getting those acks is hard).

That would be great, thanks.
