The patch titled
slab: extract __kmem_cache_destroy from kmem_cache_destroy
has been removed from the -mm tree. Its filename is

------------------------------------------------------
Subject: slab: extract __kmem_cache_destroy from kmem_cache_destroy
From: Christoph Lameter <clameter@xxxxxxx>
The ability to free memory allocated to a slab cache is also useful if an
error occurs during setup of a slab. So extract the function.
