plain text document attachment (mempool-add_kzalloc_allocator.patch) From: Matthew Dobson <colpatch@us.ibm.com> Subject: [patch 5/6] mempool - Add kzalloc allocator
Add another allocator to the common mempool code: a kzalloc/kfree allocator
This will be used by the next patch in the series to replace a mempool-backed kzalloc allocator. It is also very likely that there will be more users in the future.
