[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.
