[Kees Bos]

Public bug reported:

See also https://discuss.linuxcontainers.org/t/limits-kernel-memlock-
cannot-exceed-16777216/4856/5

In containers, the limits.kernel.memlock cannot exceed 16777216 when the
container is bionic. The memlock setting is set to 16M in systemd and
cannot be bumped up in an unprivileged container.

This is fixed in upstream systemd.

Container ubuntu version:
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.2 LTS
Release:	18.04
Codename:	bionic

systemd package version: 237-3ubuntu10.21
