      Pull more block updates from Jens Axboe:
       "This is a followup for block changes, that didn't make the initial
        pull request. It's a bit of a mixed bag, this contains:
      
         - A followup pull request from Sagi for NVMe. Outside of fixups for
           NVMe, it also includes a series for ensuring that we properly
           quiesce hardware queues when browsing live tags.
      
         - Set of integrity fixes from Dmitry (mostly), fixing various issues
           for folks using DIF/DIX.
      
         - Fix for a bug introduced in cciss, with the req init changes. From
           Christoph.
      
         - Fix for a bug in BFQ, from Paolo.
      
         - Two followup fixes for lightnvm/pblk from Javier.
      
         - Depth fix from Ming for blk-mq-sched.
      
         - Also from Ming, performance fix for mtip32xx that was introduced
           with the dynamic initialization of commands"
