Subject: [PATCH v2 0/3] cgroup: Iterate tasks that did not finish do_exit()
Date: Fri, 24 Jan 2020 12:40:14 +0100
Message-ID: <20200124114017.8363-1-mkoutny@suse.com> (raw)
In-Reply-To: <20200120145635.GA30904@blackbody.suse.cz>

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/20200117151533.12381-1-mkoutny@suse.com/
- 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
