    Merge branch 'for-linus' of git://git.kernel.dk/linux-block · 4ce01c51
    Linus Torvalds authored
    Pull block layer fixes from Jens Axboe:
     "A round of fixes/updates for the current series.
    
      This looks a little bigger than it is, but that's mainly because we
      pushed the lightnvm enabled null_blk change out of the merge window so
      it could be updated a bit.  The rest of the volume is also mostly
      lightnvm.  In particular:
    
       - Lightnvm.  Various fixes, additions, updates from Matias and
         Javier, as well as from Wenwei Tao.
    
       - NVMe:
            - Fix for potential arithmetic overflow from Keith.
            - Also from Keith, ensure that we reap pending completions from
              a completion queue before deleting it.  Fixes kernel crashes
              when resetting a device with IO pending.
            - Various little lightnvm related tweaks from Matias.
    
       - Fixup flushes to go through the IO scheduler, for the cases where a
         flush is not required.  Fixes a case in CFQ where we would be
         idling and not see this request, hence not break the idling.  From
         Jan Kara.
    
       - Use list_{first,prev,next} in elevator.c for cleaner code.  From
         Gelian Tang.
    
       - Fix for a warning trigger on btrfs and raid on single queue blk-mq
         devices, where we would flush plug callbacks with preemption
         disabled.  From me.
    
       - A mac partition validation fix from Kees Cook.
    
       - Two merge fixes from Ming, marked stable.  A third part is adding a
         new warning so we'll notice this quicker in the future, if we screw
         up the accounting.
    
       - Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes"
