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...
