[PATCH v4 0/5] virtio pmem driver
This patch series has implementation for "virtio pmem".
"virtio pmem" is fake persistent memory(nvdimm) in guest
which allows to bypass the guest page cache. This also
implements a VIRTIO based asynchronous flush mechanism.
Sharing guest kernel driver in this patchset with the
changes suggested in v3. Tested with Qemu side device
emulation [6] for virtio-pmem.
