Ah, right -- aufs is compiled as a dedicated package via dkms, it is not part of the Debian kernel. Sorry for the confusion. The sources for that are at <https://packages.debian.org/source/stable/aufs>. >>> S Sun Dec 10 12:10:27 2017 p4 kernel: WARNING: CPU: 0 PID: 1490 at >>> /var/lib/dkms/aufs/4.9+20161219/build/fs/aufs/cpup.c:423 >>> au_cp_regular+0x16c/0x250 [aufs] >>> S Sun Dec 10 12:10:27 2017 p4 kernel: .wh..wh.setup_maker_elements-i.ri.0007 >>> Please report this warning to aufs-users ML > > This is an unexpected situation for aufs.
