From 316ce2ba8e74a7bb9153b9f93adc883cb1ceb9fd Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 14 May 2010 21:30:48 +0200 Subject: [PATCH] fs/ocfs2/dlm: Use kstrdup 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/) // @@ 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 || ...)
