Hold off applying this patch, as test kernel didn't boot with this patch

Commit ec9eeb89e60d86 is just a snapshot of the Linus' tree. You should
use for-next/for-6.11 tag as a base.
Patch works fine when applied on branch for-6.11.
(This snapshot of the Linus' tree seems to be at fault).
I would still like feedback on, if this code (for detecting "root" cgrp)
is correct? :
static inline bool cgroup_is_root(struct cgroup *cgrp)
{
return cgroup_parent(cgrp) == NULL;
}
Next step for me is to backport and deploy this on a subset of
production servers.
