fs/reiserfs/ibalance.c: In function 'balance_internal':
fs/reiserfs/ibalance.c:1156:2: warning: 'new_insert_key' may be used uninitialized in this function [-Wmaybe-uninitialized]
memcpy(new_insert_key_addr, &new_insert_key, KEY_SIZE);
gcc version 5.3.1 20151219 (Ubuntu 5.3.1-4ubuntu1)

It seems unlikely in practice that new_insert_key will get used before being set,
but I can see how the compiler might think that.
