From d739b42b82773206297db1fc0d96ef895a5d9688 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 1 Feb 2006 03:06:43 -0800 Subject: [PATCH] [PATCH] reiserfs: remove kmalloc wrapper Remove kmalloc() wrapper from fs/reiserfs/. Please note that a reiserfs /proc entry format is changed because kmalloc statistics is removed.
