----------------------------------------------------------------
- Some request-based DM core and DM multipath fixes and cleanups

- Constify a few variables in DM core and DM integrity

- Add bufio optimization and checksum failure accounting to DM integrity

- Fix DM integrity to avoid checking integrity of failed reads

- Fix DM integrity to use init_completion

- A couple DM log-writes target fixes

- Simplify DAX flushing by eliminating the unnecessary flush abstraction
  that was stood up for DM's use.
