Subject: ext4 on s390?

Just wondering if anyone has tested ext4 on s390.  I see that some
assembly bitops got fixed upstream, but even with those in place I'm
hanging when ext4 tries to init bg's:

I'm now struggling to get an s390 booted on an upstream kernel to test
that, but I know about -><- about s390s.
