Bug description:
  A team within Microsoft is running the linux-azure Ubuntu kernel on a
  large AI cluster.  They are hitting an issue which is resolved by the
  following commit:

  https://github.com/torvalds/linux/commit/ebaf39e6032faf77218220707fc3fa22487784e0

  
  The bug is that threads can get stuck in the kernel. This bug can happen when removing network namespaces. This is something docker swarm does anytime it removes a container.

  Commit ebaf39e6032f was added to the mainline kernel tree in
  v4.20-rc6. It was not cc’d to upstream stable, so only v4.20-rc6 and
  newer kernels will have it.

  A test kernel was built with this commit, which resolves the issue.
