Subject: [RESEND PATCH v3 3/3] mm: increase totalram_pages when free pages allocated by bootmem allocator
Date: Tue, 15 Jan 2013 23:18:17 +0800 [thread overview]
Message-ID: <1358263097-11038-3-git-send-email-jiang.liu@huawei.com> (raw)
In-Reply-To: <1358263097-11038-1-git-send-email-jiang.liu@huawei.com>
Function put_page_bootmem() is used to free pages allocated by bootmem
allocator, so it should increase totalram_pages when freeing pages into
the buddy system.
