Hello, Andrea! Thanks a lot for your attention to this problem!
This patch lightly relies on AUFS. All that we need is https://github.com/JPyke3/mbp-manjaro-kernel/blob/master/aufs5-mmap.patch to bring needed helpers. Can we keep these changes in ubuntu sauce after AUFS will be dropped? Please, reach me if it's needed to prepare some patches to the Ubuntu kernel and send it from our (CRIU project) side.
