From 2bb06038d0dfb47acb64de01a13a7bf963d216f4 Mon Sep 17 00:00:00 2001 From: Malahal Naineni Date: Sun, 9 Sep 2012 10:25:47 -0500 Subject: [PATCH] NFSD: pass null terminated buf to kstrtouint() commit 9959ba0c241a71c7ed8133401cfbbee2720da0b5 upstream. The 'buf' is prepared with null termination with intention of using it for this purpose, but 'name' is passed instead! Signed-off-by: Malahal Naineni Signed-off-by: J.
