[RFC PATCH 06/13] vsock: add 'struct vsock_sock *' param to vsock_core_get_transport()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since now the 'struct vsock_sock' object contains a pointer to
the transport, this patch adds a parameter to the
vsock_core_get_transport() to return the right transport
assigned to the socket.

This patch modifies also the virtio_transport_get_ops(), that
uses the vsock_core_get_transport(), adding the
'struct vsock_sock *' parameter.
