    Pull device mapper updates from Mike Snitzer:
    
     - various fixes and improvements to request-based DM and DM multipath
    
     - some locking improvements in DM bufio
    
     - add Kconfig option to disable the DM block manager's extra locking
       which mainly serves as a developer tool
    
     - a few bug fixes to DM's persistent-data
    
     - a couple changes to prepare for multipage biovec support in the block
       layer
    
     - various improvements and cleanups in the DM core, DM cache, DM raid
       and DM crypt
    
     - add ability to have DM crypt use keys from the kernel key retention
       service
    
     - add a new "error_writes" feature to the DM flakey target, reads are
       left unchanged in this mode
