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

./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.

Hi Roman,

Generally these have been broken for a while, or in the case of generic/396 and
generic/399 are new tests which are exposing bugs.  A few of these I was already
aware of but just haven't had time to get to:

- the failure of generic/347 in data journalling mode is intermittent
- the failure of generic/396 in "adv" mode is related to the use of the inline
  data feature, apparently caused by ext4_convert_inline_data() corrupting an
  empty directory
- failure of generic/399 in some configurations

If you're interested in looking into any of these failing tests and either
fixing the kernel or fixing the test as appropriate, please feel free to!

Thanks,

Eric
