    Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
    
    Pull libnvdimm fixes from Dan Williams:
     "None of these are showstoppers for 4.10 and could wait for 4.11 merge
      window, but they are low enough risk for this late in the cycle and
      the fixes have waiting users . They have received a build success
      notification from the 0day robot, pass the latest ndctl unit tests,
      and appeared in next:
    
       - Fix a crash that can result when SIGINT is sent to a process that
         is awaiting completion of an address range scrub command. We were
         not properly cleaning up the workqueue after
         wait_event_interruptible().
    
       - Fix a memory hotplug failure condition that results from not
         reserving enough space out of persistent memory for the memmap. By
         default we align to 2M allocations that the memory hotplug code
         assumes, but if the administrator specifies a non-default
         4K-alignment then we can fail to correctly size the reservation.
    
       - A one line fix to improve the predictability of libnvdimm block
         device names. A common operation is to reconfigure /dev/pmem0 into
         a different mode. For example, a reconfiguration might set a new
         mode that reserves some of the capacity for a struct page memmap
         array. It surprises users if the device name changes to
         "/dev/pmem0.1" after the mode change and then back to /dev/pmem0
         after a reboot.
    
       - Add 'const' to some function pointer tables"
