Hi Richard,
I'm interested in fixing the ext2_truncate problems, as there do seem to be race conditions galore there. If you're able to replicate the problems, would you be willing to run a diagnostic patch? I think I have an idea of what's wrong, but would like to confirm it before making any substantive changes.
Regards, Bill
