Subject: [PATCH net-next 17/21] rxrpc: Differentiate PING ACK transmission traces.
Date: Fri, 1 Mar 2024 16:37:49 +0000 [thread overview]
Message-ID: <20240301163807.385573-18-dhowells@redhat.com> (raw)
In-Reply-To: <20240301163807.385573-1-dhowells@redhat.com>
There are three points that transmit PING ACKs and all of them use the same
trace string. Change two of them to use different strings.
