Subject: [PATCH] kernel: add support for NFSv4

To: openwrt-devel@lists.openwrt.org

This work is based on Daniel Colascione's submission to the OpenWrt
devel mailing list on January 15th, 2014. I modified his patch so that
it applied to the current OpenWrt Barrier Breaker tree.

Signed-off-by: W. Michael Petullo <mike@flyn.org>
