Ext3 users - Jul 2001 - 0.0.7a + rh2.2.19: help solve rejects

I get 2 rejects applying 2.2.19-ext3 to latest errata rh 2.2.19 kernel.

1)
fs/buffer.c

Should I put "J_ASSERT(buf->b_count > 0);" before or after
" *(int *)0 = 0;"?

===== ext3 0.0.7a patch

    if (buf->b_count) {
        buf->b_count--;

&& buf->b_jlis
t != BJ_Data))
+           J_ASSERT (!test_bit(BH_JWrite, &buf->b_state));
        return;
    }
    printk("VFS: brelse: Trying to free free buffer\n");
+   J_ASSERT(buf->b_count > 0);
  }

    }
    printk("VFS: brelse: Trying to free free buffer\n");
    *(int *)0 = 0;
}
 

2)
include/linux/fs.h

Can I still just increase by one from BH_Temp on as advised here
