[ 03/62] NFSD: pass null terminated buf to kstrtouint()

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Malahal Naineni <malahal@xxxxxxxxxx>

commit 9959ba0c241a71c7ed8133401cfbbee2720da0b5 upstream.

The 'buf' is prepared with null termination with intention of using it for
this purpose, but 'name' is passed instead!
