I believe I'm seeing the same issue with next-20190902 in a Linux VM
running on Hyper-V (next-20190830 is good).

git-bisect points to the same commit in linux-next:
    e013ec23b823 ("fs/namei.c: keep track of nd->root refcount status")

I can reproduce the issue every time I reboot the system.

Thanks,
