#     Merge tag 'libnvdimm-for-4.18' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
#     
#     Pull libnvdimm updates from Dan Williams:
#      "This adds a user for the new 'bytes-remaining' updates to
#       memcpy_mcsafe() that you already received through Ingo via the
#       x86-dax- for-linus pull.
#     
#       Not included here, but still targeting this cycle, is support for
#       handling memory media errors (poison) consumed via userspace dax
#       mappings.
#     
#       Summary:
#     
#        - DAX broke a fundamental assumption of truncate of file mapped
#          pages. The truncate path assumed that it is safe to disconnect a
#          pinned page from a file and let the filesystem reclaim the physical
#          block. With DAX the page is equivalent to the filesystem block.
#          Introduce dax_layout_busy_page() to enable filesystems to wait for
#          pinned DAX pages to be released. Without this wait a filesystem
#          could allocate blocks under active device-DMA to a new file.
#     
#        - DAX arranges for the block layer to be bypassed and uses
#          dax_direct_access() + copy_to_iter() to satisfy read(2) calls.
#          However, the memcpy_mcsafe() facility is available through the pmem
#          block driver. In order to safely handle media errors, via the DAX
#          block-layer bypass, introduce copy_to_iter_mcsafe().
#     
#        - Fix cache management policy relative to the ACPI NFIT Platform
#          Capabilities Structure to properly elide cache flushes when they
#          are not necessary. The table indicates whether CPU caches are
#          power-fail protected. Clarify that a deep flush is always performed
#          on REQ_{FUA,PREFLUSH} requests"
