ocfs2: Fix system inodes cache overflow.
When we store system inodes cache in ocfs2_super, we use a array for global system inodes. But unfortunately, the range is calculated wrongly which makes it overflow and pollute ocfs2_super->local_system_inodes. This patch fix it by setting the range properly. The corresponding bug is ossbug1303. http://oss.oracle.com/bugzilla/show_bug.cgi?id=1303 Cc: stable@kernel.org Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: Joel Becker <joel.becker@oracle.com>
