From 04aadf36de625647c72ec24c7e901896dd2a99e6 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 17 Oct 2010 21:56:15 +0200 Subject: jffs2: use kmemdup Convert a sequence of kmalloc and memcpy to use kmemdup. The semantic patch that performs this transformation is: (http://coccinelle.lip6.fr/) // @@ expression a,flag,len; expression arg,e1,e2; statement S; @@ a = - \(kmalloc\|kzalloc\)(len,flag) + kmemdup(arg,len,flag) <... when != a if (a == NULL || ...) S ...> - memcpy(a,arg,len+1); // Signed-off-by: Julia Lawall Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse --- fs/jffs2/dir.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'fs/jffs2') diff --git a/fs/jffs2/dir.c b/fs/jffs2/dir.c index ed78a3cf3cb0..dd745c361d7c 100644 --- a/fs/jffs2/dir.c +++ b/fs/jffs2/dir.c @@ -367,7 +367,7 @@ static int jffs2_symlink (struct inode *dir_i, struct dentry *dentry, const char } /* We use f->target field to store the target path. */ - f->target = kmalloc(targetlen + 1, GFP_KERNEL); + f->target = kmemdup(target, targetlen + 1, GFP_KERNEL); if (!f->target) { printk(KERN_WARNING "Can't allocate %d bytes of memory\n", targetlen + 1); mutex_unlock(&f->sem); @@ -376,7 +376,6 @@ static int jffs2_symlink (struct inode *dir_i, struct dentry *dentry, const char goto fail; } - memcpy(f->target, target, targetlen + 1); D1(printk(KERN_DEBUG "jffs2_symlink: symlink's target '%s' cached\n", (char *)f->target)); /* No data here.
