Subject: [PATCH 1/2] zram: use size_t instead of u16
Date: Mon, 30 Jun 2014 11:54:38 +0900 [thread overview]
Message-ID: <1404096879-24529-1-git-send-email-minchan@kernel.org> (raw)
Some of arch(ex, hexagon and PowerPC) could use PAGE_SHIFT
as 16 above. In the case, u16 is is lack of representing
compressed page's size so use size_t.
