later merged with 'for-4.8/core' to pickup the QUEUE_FLAG_DAX commits
that DM depends on to provide its DAX support
- clean up the bio-based vs request-based DM core code by moving the
request-based DM core code out to dm-rq.[hc]
- reinstate bio-based support in the DM multipath target (done with the
idea that fast storage like NVMe over Fabrics could benefit) -- while
preserving support for request_fn and blk-mq request-based DM mpath
- SCSI and DM multipath persistent reservation fixes that were
coordinated with Martin Petersen.
- the DM raid target saw the most extensive change this cycle; it now
provides reshape and takeover support (by layering ontop of the
corresponding MD capabilities)
- DAX support for DM core and the linear, stripe and error targets
- A DM thin-provisioning block discard vs allocation race fix that
addresses potential for corruption
- A stable fix for DM verity-fec's block calculation during decode
- A few cleanups and fixes to DM core and various targets
