| * find_first_zero_bit - find the first cleared bit in a memory region
| * @addr: The address to start the search at
| * @size: The maximum number of bits to search
| * Returns the bit number of the first cleared bit.
| * If no bits are zero, returns @size.
"If no bits are zero, returns @size or a number larger than @size."
