Subject: [PATCH net-next 12/21] rxrpc: Move rxrpc_send_ACK() to output.c with rxrpc_send_ack_packet()
Date: Fri, 1 Mar 2024 16:37:44 +0000 [thread overview]
Message-ID: <20240301163807.385573-13-dhowells@redhat.com> (raw)
In-Reply-To: <20240301163807.385573-1-dhowells@redhat.com>
Move rxrpc_send_ACK() to output.c to so that it is with
rxrpc_send_ack_packet() prior to merging the two.
