plain text document attachment (mempool-use_kzalloc_allocator.patch) From: Matthew Dobson <colpatch@us.ibm.com> Subject: [patch 6/6] mempool - Use common mempool kzalloc allocator
This patch changes a mempool user, which is basically just a wrapper around kzalloc(), to use the common mempool_kmalloc/kfree, rather than its own wrapper function, removing duplicated code.
