    Merge tag 'for-4.14/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
    
    Pull device mapper updates from Mike Snitzer:
    
     - 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.
