What git tree is 10d7902fa0e82b from?

I just tried reproducing it via "gce-xfstests --pmem-device shell"
with a downgraded e2fsprogs to stock upstream 1.42.12, and I can't
reproduce it with the ext4.git tree. I'm not sure whether the git
commit is critical, though. Is this a regression that was working
before?
Or it's possible that Red Hat did something weird with the CentOS 6
e2fsprogs....
