[PATCH -next 1/2] PM: hibernate: fix spelling mistake for annotation

From: TGSP
Date: Mon Oct 31 2022 - 22:29:01 EST


From: xiongxin <xiongxin@xxxxxxxxxx>

The actual calculation formula in the code below is:

max_size = (count - (size + PAGES_FOR_IO)) / 2
- 2 * DIV_ROUND_UP(reserved_size, PAGE_SIZE);

But function comments are written differently, the comment is wrong?

By the way, what exactly do the "/ 2" and "2 *" mean?
