[69/74] kernel/cred.c: use kmem_cache_free

[Greg KH]

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Julia Lawall <julia@xxxxxxx>

commit b8a1d37c5f981cdd2e83c9fd98198832324cd57a upstream.

Free memory allocated using kmem_cache_zalloc using kmem_cache_free rather
than kfree.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@
expression x,E,c;
@@

 x = \(kmem_cache_alloc\|kmem_cache_zalloc\|kmem_cache_alloc_node\)(c,...)
 ... when != x = E
     when != &x
?-kfree(x)
+kmem_cache_free(c,x)
// </smpl>
