The rxrpc_transport struct is now redundant, given that the rxrpc_peer struct is now per peer port rather than per peer host, so get rid of it. Service connection lists are transferred to the rxrpc_peer struct, as is the conn_lock. Previous patches moved the client connection handling out of the rxrpc_transport struct and discarded the connection bundling code. Signed-off-by: David Howells <dhowells@redhat.com>
