Subject: [PATCH 10/13] ext4: pass verify_reserved_gdb() the number of group decriptors
Date: Thu, 11 Aug 2011 11:28:25 +0800 [thread overview]
Message-ID: <1313033308-882-11-git-send-email-xiaoqiangnk@gmail.com> (raw)
In-Reply-To: <1313033308-882-1-git-send-email-xiaoqiangnk@gmail.com>
The 64bit resizer adds a flex group each time, so verify_reserved_gdb can
not use s_groups_count directly, it should use the number of group decriptors
before the added group.
