Subject: [PATCH 04/41] VSOCK: transport-specific vsock_transport functions
|
|
|
|
struct vsock_transport contains function pointers called by AF_VSOCK
|
|
core code. The transport may want its own transport-specific function
|
|
pointers and they can be added after struct vsock_transport.
|
|
|
|
Allow the transport to fetch vsock_transport. It can downcast it to
|
|
access transport-specific function pointers.
|
|
|
|
The virtio transport will use this.
|
|
