Subject: [PATCH 9/9] mdadm/grow: correct size and chunk_size casting
With commit 4b74a905a67e
("mdadm/grow: Component size must be larger than chunk size") mdadm returns
incorrect message if size given to grow was greater than 2 147 483 647 K.
Cast chunk_size to "unsigned long long" instead of casting size to "int".
