Merge tag 'libnvdimm-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams: "The bulk of this has been in -next since before the merge window opened, with no known collisions / issues reported. The only detail worth noting, outside the summary below, is that the "libnvdimm-start-pad" topic has been truncated to just cleanups and small fixes. The full topic branch would have doubled down on hacks around the "section alignment" limitation of the core-mm, instead effort is now being spent to address that root issue in the memory hotplug implementation for v5.2. - Fix nfit-bus command submission regression - Support retrieval of short-ARS results if the ARS state is "requires continuation", and even if the "no_init_ars" module parameter is specified - Allow busy-polling of the kernel ARS state by allowing root to reset the exponential back-off timer - Filter potentially stale ARS results by tracking query-ARS relative to the previous start-ARS - Enhance dax_device alignment checks - Add support for the Hyper-V family of device-specific-methods (DSMs) - Add several fixes and workarounds for Hyper-V compatibility - Fix support to cache the dirty-shutdown-count at init" * tag 'libnvdimm-for-5.1' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (25 commits) libnvdimm/namespace: Clean up holder_class_store() libnvdimm/of_pmem: Fix platform_no_drv_owner.cocci warnings acpi/nfit: Update NFIT flags error message libnvdimm/btt: Fix LBA masking during 'free list' population libnvdimm/btt: Remove unnecessary code in btt_freelist_init libnvdimm/pfn: Remove dax_label_reserve dax: Check the end of the block-device capacity with dax_direct_access() nfit/ars: Avoid stale ARS results nfit/ars: Allow root to busy-poll the ARS state machine nfit/ars: Introduce scrub_flags nfit/ars: Remove ars_start_flags nfit/ars: Attempt short-ARS even in the no_init_ars case nfit/ars: Attempt a short-ARS whenever the ARS state is idle at boot acpi/nfit: Require opt-in for read-only label configurations libnvdimm/pmem: Honor force_raw for legacy pmem regions libnvdimm/pfn: Account for PAGE_SIZE > info-block-size in nd_pfn_init() libnvdimm: Fix altmap reservation size calculation libnvdimm, pfn: Fix over-trim in trim_pfn_device() acpi/nfit: Fix bus command validation libnvdimm/dimm: Add a no-BLK quirk based on NVDIMM family ...
