dataplane: add virtio-blk data plane code
virtio-blk-data-plane is a subset implementation of virtio-blk. It onlyhandles read, write, and flush requests. It does this using a dedicatedthread that executes an epoll(2)-based event loop and processes I/O...
dataplane: add virtqueue vring code
The virtio-blk-data-plane cannot access memory using the usual QEMUfunctions since it executes outside the global mutex and the memory APIsare this time are not thread-safe.
