Subject: [PATCH net 0/2] vsock: don't allow half-closed socket in the host transports

We are implementing a test suite for the VSOCK sockets and we discovered
that vmci_transport never allowed half-closed socket on the host side.

As Jorgen explained [1] this is due to the implementation of VMCI.

Since we want to have the same behaviour across all transports, this
series adds a section in the "Implementation notes" to exaplain this
behaviour, and changes the vhost_transport to behave the same way.
