Hi,

This patch series enables DAX support for virtio-fs filesystem. Patches
are based on 5.3-rc5 kernel and need first patch series posted for
virtio-fs support with subject "virtio-fs: shared file system for virtual
machines".

https://www.redhat.com/archives/virtio-fs/2019-August/msg00281.html

Enabling DAX seems to improve performance for most of the operations
in general a great deal. I have reported performance numbers in first patch
series so I am not repeating these here.

Any comments or feedback is welcome.

Thanks
Vivek
