Hi,
thanks for your feedback. I'm sending updated solution that changes task
iteration to be consistent with cgroup_is_populated() check and moving the
responsibility to check PF_EXITING on the consumers of iterator API.

Changes from v1
- v1: https://lore.kernel.org/lkml/[e-mail]/
- Swap the fixing and refactoring patch (in order to make the fix easier for
  backport)
- Don't introduce tasks lists array because of unnecessarily long access code
- Fix comment in selftest
- I leave the CC:stable on discretion of the maintainer
