From 0cfc11ed45e4c00750039e5a18c0fc0d681e19db Mon Sep 17 00:00:00 2001 From: Carsten Otte Date: Wed, 27 Jul 2005 11:43:52 -0700 Subject: [PATCH] [PATCH] fix xip sparse file handling in ext2 Oliver Paukstadt from our test department is testing the xip patches in Linus' git-tree. He found a problem that shows when reading a file that contains sparse blocks (holes) on a -o xip mounted ext2 filesystem: the BUG_ON() in fs/ext2/xip.c:40 triggers where it should not. The problem was introduced by a cleanup in my previous patch, this patch fixes it.
