I did run e.g. ext4/4k, ext4/1k, ext4/nojournal, ext4/datajournal. But
my setup does not run ext4/026 (too old e2fsprogs it seems - I need to
update those). I have cathegorized generic/233 as preexisting failure but I
might be wrong and it definitely failed differently for me. Anyway, thanks
for running these tests, I'll check more what's going on.
