From 1d1afcbc294cc7c788eb5c7b6b98e8d63caf002c Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 9 May 2012 14:04:55 -0400 Subject: [PATCH] NFS: Clean up - Rename nfs_unlock_request and nfs_unlock_request_dont_release Function rename to ensure that the functionality of nfs_unlock_request() mirrors that of nfs_lock_request(). Then let nfs_unlock_and_release_request() do the work of what used to be called nfs_unlock_request()...
