[overlayfs/bug] LXC ephemeral containers have "/rootfs" prefix in /proc/self/maps entries

We met a LXC issue [1] with overlayfs in Ubuntu, but with aufs it is gone.

I suspect it's related to the issue you mentioned in Documentation of overlayfs:
Symlinks in /proc/PID/ and /proc/PID/fd which point to a non-directory
object in overlayfs will not contain vaid absolute paths, only
relative paths leading up to the filesystem's root.  This will be
fixed in the future.

Could you please help to take a look at this? or point me out some hints.
