From 53184082b070dfb077218828fdf839826102ed96 Mon Sep 17 00:00:00 2001 From: Matthew Dobson Date: Sun, 26 Mar 2006 01:37:46 -0800 Subject: [PATCH] mempool: add kmalloc allocator Add another allocator to the common mempool code: a kmalloc/kfree allocator This will be used by the next patch in the series to replace duplicate mempool-backed kmalloc allocators in several places in the kernel. It is also very likely that there will be more users in the future.
