I retested the following configurations on 69973b830859 ("Linux 4.9"):

./kvm-xfstests.sh -c nojournal    ext4/301
./kvm-xfstests.sh -c ext3conv     generic/347
./kvm-xfstests.sh -c adv          generic/396 generic/399
./kvm-xfstests.sh -c data_journal generic/347
./kvm-xfstests.sh -c bigalloc     generic/399
./kvm-xfstests.sh -c bigalloc_1k  generic/273

all of the tests from list have failed.

This is not very much helpful, but at least that can be a starting
point for bisecting.

When there was a successful xfstests run at least for some of
the configurations?  Would be nice to have a "good" reference.
