Date: Thu, 14 Jan 2021 16:08:17 +0900 From: Daeseok Youn <daeseok.youn@...il.com> To: rppt@...nel.org, akpm@...ux-foundation.org, linux-mm@...ck.org, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH] mm: memblock: remove return value of memblock_free_all() No one checks the return value of memblock_free_all(). Make the return value void. memblock_free_all() is used on mem_init() for each architecture, and the total count of freed pages will be added to _totalram_pages variable by calling totalram_pages_add(). so do not need to return total count of freed pages.
