i'm running 3.18.50-vs2.3.7.5 and will put into production
3.18.51-vs2.3.7.5 later this week, having already tested it.

my testing consists of, (with ext[234]), and
creating a basic set of device files (eg null, ptmx, random, tty,
urandom) within a vserver where device permissions are enforced by
cgroup's devices.{allow,deny} (which is a use-case that silently broke
with a previous linux-vserver + upstream update iteration, so i added
it as a check-out test.)

still need to figure out why jessie lxc containers can only use a
single tty and only once (eg can't log into container twice
successively or simultaneously), but that happens on vanilla 3.18,
too. (need to try switching the container's init from systemd to sysv
the next time i experiment/debug.)
