This isn't about individual drivers, as I showed from the udev rules used by Fedora/Redhat it is clearly entire subsystems and hundreds of drivers that desire this. Ulf can certainly decide what is best for the MMC and memstick drivers. Thus I think it is probably best to make each subsystem that desire BFQ imply it. Yours, Linus Walleij
