Title:
  Processes in "D" state due to zap_pid_ns_processes kernel call with
  Ubuntu + Docker

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Xenial:
  Fix Released
Status in linux source package in Yakkety:
  Fix Released
Status in linux source package in Zesty:
  Fix Released

Bug description:
  SRU Justification

  Impact: In some cases some docker processes can be stuck in the D
  state after a container has terminated. They will remain in this state
  until reboot.

  Fix: Cherry pick upstream commit
  b9a985db98961ae1ba0be169f19df1c567e4ffe0, which has already been
  included as a stable commit in maintained upstream stable kernels.

  Test case: See below.

  Regression potential: Low, this is a simple change and as stated above
  the patch has already been shipped out in upstream stable kernels.

  (please refer to
  https://github.com/moby/moby/issues/31007#issuecomment-308877825 for
  context)

  Precondition: Ubuntu 16.04.2 with Docker 17.03 (kernel 4.4)

  Steps to reproduce:
  - Install latest Docker
  - Run 300 containers with health check (for i in {1..300}; do docker run -d -it --restart=always --name poc_$i talves/health_poc; done)
  - Send termination signal to the containers (docker kill -s TERM $(docker ps -q)
  - A few processes are going to be stuck in "uninterruptible sleep" ("D" state). The only know way to recover from this is host reboot

  Expected behavior:
  - All containers should be terminated without any dangling process

  Actual behavior:
  - Some processes are left in "D" state. In our production environment this leads over time to performance degradation and maintenance issues due to containers that cannot be stopped / removed.

  A fix is provided on kernel 4.12 - it would be nice if it could be
  backported and included in the next Ubuntu release within the
  supported kernel.

  Thanks in advance
