Over this summer, I have been working on implementing journaling for the ext filesystem. This journaling feature is to be compatible with linux's implementation thus the on disk format of the journal metadata is the same. Most of the ext filesystem operations are journaled now, however truncate is still tricky to get right and needs to be reviewed and tested more. Currently extents are not journaled so only ext3 is supported for journaling. Some more testing with fsx and other scripts are needed and comprehensive crash simulations are still needed. Pau Sum
