Darrick these corruption tests you added to xfstests last year all
fail the same way with DAX enabled. They spew:
"pwrite64: Structure needs cleaning"
...reports that are cleaned up by running without "-o dax".
Alternatively you could sit back and watch me try to figure it out,
that should be quite entertaining... as a start I'll try to pin down a
stack trace when the error is returned.
