Hi,
On latest Linus tree, xfstests generic/04{4,5,6} fails.
FSTYP -- ext4

Yes, that's known issue. generic/04[456] were originally XFS specific
tests, and they have have assumptions about the implementation of the
underlying file system.
We have a few of those at the moment in kvm-xfstests/gce-xfstests's
exclude file:
https://git.kernel.org/cgit/fs/ext2/xfstests-bld.git/tree/kvm-xfstests/test-appliance/files/root/fs/ext4/exclude
# generic/042 and generic/392 are failing because ext4 forces the
# resolution of all delayed allocation writes before allowing the
# punch operation to proceed. We probably want to see if we can avoid
# this for the future, but what ext4 is doing is legal, so just skip
# the test for now
generic/042
generic/392
# generic/04[456] tests how truncate and delayed allocation works
# ext4 uses the data=ordered to avoid exposing stale data, and
# so it uses a different mechanism than xfs. So these tests will fail
generic/044
generic/045
generic/046
# generic/223 tests file alignment, which works on ext4 only by
# accident because we're not RAID stripe aware yet, and works at all
# because we have bias towards aligning on power-of-two block numbers.
# It is a flaky test for some configurations, so skip it.
generic/223
# ext4/304 fails for all configurations, and this appears to be at
# test or fio bug.
#
ext4/304
Cheers,
