cgroup2: use new fstype for unified hierarchy
|
||||
|
||||
Since Linux v4.4-rc1, __DEVEL__sane_behavior does not exist anymore and
|
||||
is replaced by a new fstype "cgroup2".
|
||||
|
||||
With this patch, systemd no longer supports the old (unstable) way of
|
||||
doing unified hierarchy with __DEVEL__sane_behavior and systemd now
|
||||
requires Linux v4.4 for unified hierarchy.
|
||||
|
||||
Non-unified hierarchy is still the default and is unchanged by this
|
||||
patch.
