From 79d4e1f0d8910f0214a57832ca6d589640d572c0 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 21 May 2012 22:44:31 -0400 Subject: [PATCH] NFS: Use proper naming conventions for NFSv4.1 server scope fields Clean up: When naming fields and data types, follow established conventions to facilitate accurate grep/cscope searches. Additionally, for consistency, move the scope field into the NFSv4- specific part of the nfs_client, and free that memory in the logic that shuts down NFSv4 nfs_clients. Introduced by commit 99fe60d0 "nfs41: exchange_id operation", April 1 2009.
