Looked at it just now and all seems sane.
The reference to init_tasks threw me off at first. I initially thought
you're talking about pid namespace inits but you mean tasks created via
fork_idle() here. Since those tasks can't be created with
CLONE_INTO_CGROUP set it's perfectly safe to set cset = NULL
unconditionally.
Thanks for fixing the merge conflict!
