Subject: [PATCH v3 10/32] svcrdma: Displayed remote IP address should match stored address
Date: Thu, 21 May 2020 10:34:36 -0400
Message-ID: <20200521143436.3557.71314.stgit@klimt.1015granger.net> (raw)
In-Reply-To: <20200521141100.3557.17098.stgit@klimt.1015granger.net>

Clean up: After commit 1e091c3bbf51 ("svcrdma: Ignore source port
when computing DRC hash"), the IP address stored in xpt_remote
always has a port number of zero. Thus, there's no need to display
the port number when displaying the IP address of a remote NFS/RDMA
client.
