From a37b06d589f2c687a38d07569f4ef97c650fde39 Mon Sep 17 00:00:00 2001 From: Doug Chapman Date: Wed, 13 May 2009 02:56:39 +0100 Subject: [PATCH] Squashfs: fix breakage when page size > metadata block size Squashfs is broken on any system where the page size is larger than the metadata size (8192). This is easily fixed by ensuring cache->pages is always > 0.
