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 v4. Tested with Qemu side device emulation [6] for virtio-pmem.

This patch series is ready to be merged via nvdimm tree as discussed with Dan. We have ack/review on XFS, EXT4 & VIRTIO patches. Need an ack on device mapper change in patch 4. Mike, Can you please review and ack patch4. This version does not has any additonal code change from v10 and is only rebase of v10 on Linux 5.2-rc4 which is required for patch4.
