One of the reasons why I want to get this fixed sooner rather than later is that even when testing a stock ext4 file system, fsstress can potentially create indirect mapped files that could then get punched. So I wonder if bug might be responsible for some of the very random failures that I've been seeing in my testing... - Ted
