Yes, XFS_SB_FEAT_INCOMPAT_BIGTIME is what is missing for the test. Device is
formatted with: -m reflink=1 (I'm sorry to not posting this before):
tst_test.c:1170: TINFO: Formatting /dev/loop0 with xfs opts='-m reflink=1' extra opts=''
I thought it would imply XFS_SB_FEAT_INCOMPAT_BIGTIME, but when I tried to remove it
it did not help:

Well, I tried with mkfs.xfs from openSUSE Leap 15.6 (tested via rapido-linux),
probably the defaults add it.
$ mkfs.xfs -V
mkfs.xfs version 6.7.0
Also I noted that test works on our 5.3.18 based SLES15-SP2 with xfsprogs
4.15.0. Maybe I'm just wasting your time with wrong patch.
Kind regards,
