I do not know if it's reasonable to expect xfstests to pass against
ext4. If it is, this is something that would need to be handled in the
kernel (not in xfsprogs, which was certainly not involved in the
creation of the filesystem). Reassigning.

extents ( ext4 )

Bug description:
xfstests fails non-zero size but no extents on ext4 filesystem
Environment
------------------
Kernel Build: 4.12.1-041201-generic
Model : 8247-22L
Platform : PowerNV ( P8 )
Uname output
-------------------
# uname -a
Linux ltc-test-ci2 4.12.1-041201-generic #201707121132 SMP Wed Jul 12
17:03:25 UTC 2017 ppc64le ppc64le ppc64le GNU/Linux
Steps to reproduce:
----------------------------------------
1. Create a loop device with ext4 filesystem
2. git clone git://git.kernel.org/pub/scm/fs/xfs/xfstests-dev.git; cd
xfstests-dev
3. make
4. Create a local.config for running with created loop device
5. Run xfstests-dev test : ./check tests/generic/044
The test 044 fails with following
generic/044 - output mismatch (see
/root/harish/xfstests-dev/results//generic/044.out.bad)

Issue does not happen when running the same test with xfs file system. (ie,
creating loop device with xfs file system).
