Subject: [RFC PATCH 9/9] mm/zswap: use highmem pages for compressed pool
Date: Tue, 14 Oct 2014 20:59:28 +0900 [thread overview]
Message-ID: <1413287968-13940-10-git-send-email-heesub.shin@samsung.com> (raw)
In-Reply-To: <1413287968-13940-1-git-send-email-heesub.shin@samsung.com>
Now that the zbud supports highmem, storing compressed anonymous pages
on highmem looks more reasonble. So, pass __GFP_HIGHMEM flag to zpool
when zswap allocates memory from it.
