From: Chuck Lever Date: Mon, 4 Jun 2018 14:53:34 +0000 (-0400) Subject: NFSv4.0: Remove transport protocol name from non-UCS client ID X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=025bb9f8720577b3815263dd961cdebe0c823080;p=openwrt%2Fstaging%2Fblogic.git NFSv4.0: Remove transport protocol name from non-UCS client ID Commit 69dd716c5ffd ("NFSv4: Add socket proto argument to setclientid") (2007) added the transport protocol name to the client ID string, but the patch description doesn't explain why this was necessary. At that time, the only transport protocol name that would have been used is "tcp" (for both IPv4 and IPv6), resulting in no additional distinctiveness of the client ID string. Since there is one client instance, the server should recognize it's state whether the client is connecting via TCP or RDMA. Same client, same lease.
