[systemd-devel] [PATCHSET RESEND] update unified hierarchy support

[Tejun Heo]

(bounced for not being subscribed, resending...)

Hello,

Unified hierarchy is available on the 4.5 kernel but there have been
several updates.

1. The __DEVEL__sane_behavior flag is gone.  Unified hierarchy is now
   available as "cgroup2" filesystem type with its own super magic
      number.

2. "cgroup.populated" file is replaced with "populated" field of
   "cgroup.events" file.

3. A zombie task remains associated with the cgroup it was associated
   with at the time of death instead of being moved immediately to
      root.  This means that pid to unit lookup may return a slice if the
         session or service unit the pid belonged to is already gone.

Three patches are attached addressing each of the above.

Thanks!
