2005-07-27[PATCH] fix xip sparse file handling in ext2Carsten Otte
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.

2005-07-15[PATCH] execute-in-place fixesCarsten Otte
This patch includes feedback from Andrew and Christoph. Thanks for taking time to review. Use of empty_zero_page was eliminated to fix compilation for architectures that don't have it. This patch removes setting pages up-to-date in ext2_get_xip_page and all bug checks to verify that the page is indeed up to date. Setting the page state on mapping to userland is bogus. None of the code patchs involved with these pages in mm cares about the page state. still on my ToDo list: identify a place outside second extended where __inode_direct_access should reside Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-24[PATCH] xip: ext2: execute in placeCarsten Otte
These are the ext2 related parts. Ext2 now uses the xip_* file operations along with the get_xip_page aop when mounted with -o xip. Signed-off-by: Carsten Otte <cotte@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
