Subject: [PATCH net-next 5/5] net/smc: remove local variable page in smc_rx_splice()
Date: Mon, 23 Jul 2018 13:53:12 +0200 [thread overview]
Message-ID: <20180723115312.54694-6-ubraun@linux.ibm.com> (raw)
In-Reply-To: <20180723115312.54694-1-ubraun@linux.ibm.com>
From: Ursula Braun <ursula.braun@de.ibm.com>
The page map address is already stored in the RMB descriptor.
There is no need to derive it from the cpu_addr value.
