[Qemu-devel] [PATCH v2 4/5] virtio-9p: add unrealize handler

This patch allows to hot-unplug a quiescent virtio-9p device, and free its allocated resources. A refcount is added to the v9fs thread pool, so that its resources are freed as well when the last virtio-9p device is unplugged. Note that we have an unplug blocker which prevents this code to be
