3.18-stable review patch. If anyone has any objections, please let me know. ------------------ From: Krzysztof Kozlowski <k.kozlowski@xxxxxxxxxxx> commit 1c1fb9b0c89a2506e556114c813a606bc1508d49 upstream. NFS client is already enabled (NFS_FS) and by default it enables clients for version 2 and 3. Enable explicitly the version 4 client to utilize the newer protocol. The NFS client is especially useful for testing kernel in automated environments (network boot with network file system).
