From 0eaae62abaa1ad1f231932b6cdd9fb1b91df6651 Mon Sep 17 00:00:00 2001 From: Matthew Dobson Date: Sun, 26 Mar 2006 01:37:47 -0800 Subject: [PATCH] mempool: use common mempool kmalloc allocator This patch changes several mempool users, all of which are basically just wrappers around kmalloc(), to use the common mempool_kmalloc/kfree, rather than their own wrapper function, removing a bunch of duplicated code.
