Hi,

These are RFC patches for adding a notification queue to allow sending
notifications from host to guest.

It also adds support for blocking remote posix locks using the newly
introduced notification queue.

These patches apply on top of 5.4-rc8 plus following patch series I had
posted a while back.

https://lkml.org/lkml/2019/10/30/493

These changes require virtio spec changes as well. I have yet to do
that.

Thanks
Vivek
