NFS: Update help text for CONFIG_NFS_FS
Clean up: refresh the help text for Kconfig items related to the NFS client. Remove obsolete URLs, and make the language consistent among the options. Also move the ROOT_NFS config option next to the options related to the NFS client. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
