Robert Elliot found a problem with not fully zeroed out UNMAP CDBs, which is fixed by the saner discard handling in that series. There is a new patch to factor the code from the above series for blk-mq use, which I've attached below. Besides that the only changes are minor merge fixups in the main blk-mq usage patch.
Be warned: both Rob Elliott and I can easily break the scsi-mq.3 branch. It seems as though a regression has slipped in. I notice that Christoph has added a new branch called "scsi-mq.3-no-rebase".
