Date: Tue, 1 Nov 2022 10:28:39 +0800 From: TGSP <tgsp002@...il.com> To: rafael@...nel.org, len.brown@...el.com, pavel@....cz, huanglei@...inos.cn Cc: linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org, xiongxin <xiongxin@...inos.cn>, stable@...r.kernel.org Subject: [PATCH -next 1/2] PM: hibernate: fix spelling mistake for annotation From: xiongxin <xiongxin@...inos.cn> 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?
