[ Upstream commit 6e5d7300cbe7c3541bc31f16db3e9266e6027b4b ]
The actual maximum image size formula in hibernate_preallocate_memory()
is as follows:
max_size = (count - (size + PAGES_FOR_IO)) / 2
- 2 * DIV_ROUND_UP(reserved_size, PAGE_SIZE);
but the one in the kerneldoc comment of the function is different and
incorrect.
