Ext4 data corruption trouble [Updated]

I also want to assure people that before I send any pull request to Linus, I have run a very extensive set of file system regression tests, using the standard xfstests suite of tests (originally developed by SGI to test xfs, and now used by most of the developers of the major, actively-maintained file systems). So for example, my development laptop, which I am currently using to post this note, is currently running v3.6.3 with the ext4 patches which I have pushed to Linus for the 3.7 kernel. Why am I willing to do this? Specifically because I am constantly running a very large set of automated regression tests on a very regular basis, and certainly before sending the latest set of patches to Linus.
