Subject: mm/slab_common.c: use kmem_cache_free()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7c4da061f2e953df479b126b9263f0e845bce0ec;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mm/slab_common.c: use kmem_cache_free()

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:

@@
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)
