Subject: [PATCH v5 10/30] xprtrdma: Remove rpcrdma_memreg_ops
Date: Wed, 19 Dec 2018 10:59:01 -0500 [thread overview]
Message-ID: <20181219155901.11602.15647.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20181219155152.11602.18605.stgit@manet.1015granger.net>
Clean up: Now that there is only FRWR, there is no need for a memory
registration switch. The indirect calls to the memreg operations can
be replaced with faster direct calls.
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
