Subject: [PATCH 6/10] arch/powerpc/platforms/pseries: Use kstrdup
Date: Fri, 14 May 2010 21:30:13 +0200 (CEST) [thread overview]
Message-ID: <Pine.LNX.4.64.1005142129520.28935@ask.diku.dk> (raw)
From: Julia Lawall <julia@diku.dk>
Use kstrdup when the goal of an allocation is copy a string into the
allocated region.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression from,to;
expression flag,E1,E2;
statement S;
@@
- to = kmalloc(strlen(from) + 1,flag);
+ to = kstrdup(from, flag);
... when != \(from = E1 \| to = E1 \)
if (to==NULL || ...) S
... when != \(from = E2 \| to = E2 \)
- strcpy(to, from);
// </smpl>
