From: zhong jiang <zhongjiang@huawei.com>
when compile the kenrel code, I happens to the following warn. fs/reiserfs/ibalance.c:1156:2: warning: ‘new_insert_key’ may be used uninitialized in this function. memcpy(new_insert_key_addr, &new_insert_key, KEY_SIZE); ^ The patch just fix it to avoid the warn.
