Subject: [PATCH v1 10/22] xprtrdma: Rename rpcrdma_conn_upcall
Date: Mon, 10 Sep 2018 11:09:48 -0400 [thread overview]
Message-ID: <20180910150948.10564.95683.stgit@manet.1015granger.net> (raw)
In-Reply-To: <20180910150040.10564.97487.stgit@manet.1015granger.net>
Clean up: Use a function name that is consistent with the RDMA core
API and with other consumers. Because this is a function that is
invoked from outside the rpcrdma.ko module, add an appropriate
documenting comment.
