get_pointer() assumes the string has unspecified lifetime (at least as
long as the object is alive). In some cases we can only produce a
temporary string that should be freed when get_pointer() is done.

It can be useful to run an AioContext from a thread which normally does
not "own" the AioContext. For example, request draining can be
implemented by acquiring the AioContext and looping aio_poll() until all
requests have been completed.
The following pattern should work:

Each ioctl request of vhost-kernel has a vhost-user message equivalent,
which is sent it over the control socket.
The general approach is to copy the data from the supplied argument
pointer to a designated field in the message. If a file descriptor is
to be passed it should be placed also in the f
We introduce the concept of vhost-backend, which can be either vhost-kernel
or vhost-user. The existing vhost interface to the kernel is abstracted
behind the vhost-kernel backend.
We replace all direct ioctls to the kernel with a vhost_call to the backend.
vhost dev->control is referenced only in
At runtime vhost-user netdev will detect if the vhost backend is up or down.
Upon disconnection it will set link_down accordingly and notify virtio-net.

In this patch series we would like to introduce our approach for putting a

Add structures for passing vhost-user messages over a unix domain socket.
This is the equivalent of the existing vhost-kernel ioctls.
Connect to the named unix domain socket. The system call sendmsg
is used for communication. To be able to pass file descriptors
