I would drop "recently introduced", unless we can define a precise commit when code was added so that it can actually be checked (I know you can't since the relevant patch is part of this series and not in the mainline yet). Bjorn posted some guidelines that are helpful: https://marc.info/?l=linux-pci&m=150905742808166&w=2 I can make these changes myself, no problem but please address Russell's comment so that we can proceed.
