Patch against linux-2.4.8 is at http://www.uow.edu.au/~andrewm/linux/ext3/ The only changes here are merging up to 2.4.8 and the bigendian fix. linux-2.4.8-ac1 currently has ext3-0.9.3 which has no known crash-worthy bugs, but is old. I'm about to send Alan a diff which takes -ac up to 0.9.6. The changes between 0.9.3 and 0.9.6 may be summarised as: - Simplify the handling of
