Hi, Here are RFC patches for adding a notification queue to virtio-fs to send notifications from host to guest. It also has patches to support remote posix locks which make use of this newly introduced notification queue.
These patches apply on top of following. https://gitlab.com/virtio-fs/qemu/tree/virtio-fs-dev These change require changes in spec also. I have yet to create spec changes and that's why this is still an RFC patch series. Any feedback is appreciated.
