Which I/O controller is the fairest of them all?

Thanks Jonathan for the very nice article. There is one thing I would like to point out though. You mentioned that io-controller has the limitation that "it cannot implement different policies for different devices". This limitation can be easily fixed. In fact, at Google, we already have a (relatively simple) patch for allowing us to set different weights for different devices. And we have been testing Vivek's patches with that patch applied. We would make sure that this patch is included in the next posting by Vivek.
