Ugh sorry, I just saw this. vger is sending postings massively out of
order today.
Ignore my previous reply to #1 :-)
Michael, please provide a proper introductory posting for your patch series
just like everyone else does.
Not only does it help people understand at a high level what the patch
series is doing, how it is doing it, and why it is doing it that way. It

Yet another forward declaration I missed. Hopfully the last one ...
A bunch of drivers want to know which tx queue triggered a timeout,
and virtio wants to do the same.
We actually have the info to hand, let's just pass it on to drivers.

This patch adds a new vsock_loopback transport to handle local
communication.
This transport is based on the loopback implementation of
virtio_transport, so it uses the virtio_transport_common APIs
to interface with the vsock core.

Now that we have a transport that can handle the local communication,
we can use it when it is loaded.
A socket will use the local transport (loopback) when the remote
CID is:
- equal to VMADDR_CID_LOCAL
- or equal to transport_g2h->get_local_cid(), if transport_g2h
is loaded (this allows us to
We can remove the loopback handling from virtio_transport,
because now the vsock core is able to handle local communication
using the new vsock_loopback device.

The VMADDR_CID_RESERVED (1) was used by VMCI, but now it is not
used anymore, so we can reuse it for local communication
(loopback) adding the new well-know CID: VMADDR_CID_LOCAL.

We can remove virtio header includes, because virtio_transport_common
doesn't use virtio API, but provides common functions to interface
virtio/vhost transports with the af_vsock core, and to handle
the protocol.

So roll our own mmap function, wrapping drm_gem_shmem_mmap(), to tweak
vm_page_prot accordingly.
