<div class='commit-subject'>Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm</div><div class='commit-msg'>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"

* 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
  libnvdimm, pfn: fix memmap reservation size versus 4K alignment
  acpi, nfit: fix acpi_nfit_flush_probe() crash
  libnvdimm, namespace: do not delete namespace-id 0
  nvdimm: constify device_type structures
