From d739b42b82773206297db1fc0d96ef895a5d9688 Mon Sep 17 00:00:00 2001 From: Pekka Enberg Date: Wed, 1 Feb 2006 03:06:43 -0800 Subject: [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.

On some platforms, this causes alignment exceptions. The following patch uses the standard bitmap declaration macros to declare the bitmaps, fixing the problem. Originally from Takashi Iwai.
