    Pull block updates from Jens Axboe:
     "This is the main pull request for block IO related changes for the
      4.16 kernel. Nothing major in this pull request, but a good amount of
      improvements and fixes all over the map. This contains:
    
       - BFQ improvements, fixes, and cleanups from Angelo, Chiara, and
         Paolo.
    
       - Support for SMR zones for deadline and mq-deadline from Damien and
         Christoph.
    
       - Set of fixes for bcache by way of Michael Lyle, including fixes
         from himself, Kent, Rui, Tang, and Coly.
    
       - Series from Matias for lightnvm with fixes from Hans Holmberg,
         Javier, and Matias. Mostly centered around pblk, and the removing
         rrpc 1.2 in preparation for supporting 2.0.
    
       - A couple of NVMe pull requests from Christoph. Nothing major in
         here, just fixes and cleanups, and support for command tracing from
         Johannes.
    
       - Support for blk-throttle for tracking reads and writes separately.
         From Joseph Qi. A few cleanups/fixes also for blk-throttle from
         Weiping.
    
       - Series from Mike Snitzer that enables dm to register its queue more
         logically, something that's alwways been problematic on dm since
         it's a stacked device.
    
       - Series from Ming cleaning up some of the bio accessor use, in
         preparation for supporting multipage bvecs.
    
       - Various fixes from Ming closing up holes around queue mapping and
         quiescing.
    
       - BSD partition fix from Richard Narron, fixing a problem where we
         can't mount newer (10/11) FreeBSD partitions.
    
       - Series from Tejun reworking blk-mq timeout handling. The previous
         scheme relied on atomic bits, but it had races where we would think
         a request had timed out if it to reused at the wrong time.
    
       - null_blk now supports faking timeouts, to enable us to better
         exercise and test that functionality separately. From me.
    
       - Kill the separate atomic poll bit in the request struct. After
         this, we don't use the atomic bits on blk-mq anymore at all. From
         me.
    
       - sgl_alloc/free helpers from Bart.
    
       - Heavily contended tag case scalability improvement from me.
    
       - Various little fixes and cleanups from Arnd, Bart, Corentin,
         Douglas, Eryu, Goldwyn, and myself"
