Message-Id: <1264693423-2694-4-git-send-email-ngupta@vflare.org> Date: Thu, 28 Jan 2010 21:13:39 +0530 From: Nitin Gupta <ngupta@...are.org> To: Greg KH <greg@...ah.com> Cc: Pekka Enberg <penberg@...helsinki.fi>, linux-kernel <linux-kernel@...r.kernel.org> Subject: [PATCH 3/7] Set block size to PAGE_SIZE ramzswap block size needs to be set equal to PAGE_SIZE to avoid receiving any unaligned block I/O requests (happens due to readahead logic during swapon). These unaligned accesses produce unnecessary I/O errors, scaring users.
