From: zhong jiang <zhongji...@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.
