Message-Id: <1188488452.15770.55.camel@ext1.frec.bull.fr>
Date: Thu, 30 Aug 2007 17:40:52 +0200
From: Valerie Clement <valerie.clement@...l.net>
To: linux-ext4 <linux-ext4@...r.kernel.org>,
Theodore Ts'o <tytso@....edu>
Subject: [PATCH 6/8][e2fsprogs] change access to the filesystem blocks
counter
From: Valerie Clement <valerie.clement@...l.net>
This patch replaces all references to super->s_blocks_count by
ext2_blocks_count(super) in preparation for 64-bit support.
Signed-off-by: Valerie Clement <valerie.clement@...l.net>
