Date: Fri, 08 Feb 2008 12:51:53 -0500 From: Chuck Lever <chuck.lever@...cle.com> To: linux-kernel@...r.kernel.org Cc: linux-nfs@...r.kernel.org Subject: [PATCH 04/11] NFSD: Update help text for CONFIG_NFSD Clean up: refresh the help text for Kconfig items related to the NFS server. Remove obsolete URLs, and make the language consistent among the options.
