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
