Subject: [PATCH 0/2] block, bfq: make bfq disable iocost and present a double interface

Hi Jens,

the first patch in this series is Tejun's patch for making BFQ disable
io.cost. The second patch makes BFQ present both the bfq-prefixes
parameters and non-prefixed parameters, as suggested by Tejun [1].

In the first patch I've tried to use macros not to repeat code
twice. checkpatch complains that these macros should be enclosed in
parentheses. I don't see how to do it. I'm willing to switch to any
better solution.

Thanks,
Paolo
