At least the xfs part of this patch is broken.
Running the latest git-kernel bogofilter doesn't work anymore on my xfs
partition. When I run "bogoutil -d wordlist.db" to dump the contents of
the database, it produces no output at all. 

Reverting 02c24a82187d (or only the xfs part of that commit) "solves"
the problem.

Here is the output of "strace bogoutil -d wordlist.db":
