Merge tag 'libnvdimm-for-5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"Primarily just the virtio_pmem driver:
- virtio_pmem
The new virtio_pmem facility introduces a paravirtualized
persistent memory device that allows a guest VM to use DAX
mechanisms to access a host-file with host-page-cache. It arranges
for MAP_SYNC to be disabled and instead triggers a host fsync()
when a 'write-cache flush' command is sent to the virtual disk
device.
- Miscellaneous small fixups"
