Here, free memory is allocated using kmem_cache_zalloc. So, use
kmem_cache_free instead of kfree.
This is done using Coccinelle and semantic patch used
is as follows:
//<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>
