Subject: [patch 6/8] mempool - Use common mempool kzalloc allocator
Date: Mon, 30 Jan 2006 13:24:02 -0800 [thread overview]
Message-ID: <1138656242.20704.6.camel@localhost.localdomain> (raw)
In-Reply-To: <20060130211951.225129000@localhost.localdomain>
plain text document attachment (mempool-use_kzalloc_allocator.patch)
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.
