I mean that the I-pipe patch is made for the mainline kernel. If you
use a vendor fork, then the I-pipe patch usually does not apply and

An effort from the Raspberry pi community to mainline their code
instead of using a vendor fork. Note than doing this usually
improves the code quality, because the code gets more reviews.
