I bumped into this problem:
"...

It doesn't look you are compiling vanilla v3.18 or v3.18.21.
Please provide these necessary info

(from aufs README file)

When you have any problems or strange behaviour in aufs, please let me
know with:
:::

• linux kernel version
  if your kernel is not plain, for example modified by distributor,
  the url where i can download its source is necessary too.
• aufs version which was printed at loading the module or booting the
  system, instead of the date you downloaded.
• configuration (define/undefine CONFIG_AUFS_xxx)
• kernel configuration or /proc/config.gz (if you have it)
  :::
• mailto: aufs-users at lists.sourceforge.net

Usually, I don't watch the Public Areas(Bugs, Support Requests, Patches,
and Feature Requests) on SourceForge. Please join and write to
aufs-users ML.
