Exactly.
At the same time, I noticed that I made a mistake on my git-work. I
thought there is something wrong with the commit
e14748e 2017-02-19 UBUNTU: SAUCE: Import aufs driver
in zesty because it doesn't match the commit
6c73f3b 2017-02-04 aufs4.x-rcN 20170206
in aufs4-standalone.
But it perfectly matches. I think I made some changes in zesty tree
unwillingly during investigating this problem.
Sorry for the confusion.
But the conclusion doesn't change.
I think you found a AB-BA deadlock problem in aufs, and I am working on
it.

It looks the same issue.
