Please, don't be too fast when thinking about a revert.  Several of my
colleagues (Debian users) cling to the feature since they need it for
using the company's LXC containers; if permit_mounts_in_userns is
removed again, they might be forced to switch to non-Debian kernels or
to live-patch the kernel with fragile stuff like [1], cp. #913880.
