Hi Jens, this series contains an already proposed patch by Luca, plus six new patches. The goals of these patches are summarized in the subject of this cover letter. I'm including Luca's patch here, because it enabled the actual use of stable merge, and, as such, triggered an otherwise silent bug. This series contains also the fix for that bug ("block, bfq: avoid delayed merge of async queues"), tested by Holger [1].
Thanks, Paolo
