Hi all, here's the patcheset to enable scsi-mq support for megaraid_sas. It's based on hch's irq rework currently pending in tip. As the overall results have been less then stellar (see the thread 'reduced latency is killing performance') I've also added a module parameter 'use_blk_mq' to allowing to switch off scsi-mq support on a per-driver basis.
