Well, my understanding is that Peter is going to send v2 with some minor
changes, I am going to send this patch on top of his series.
In particular 2/2 should set GP_PASSED rather than !GP_IDLE. It would be
nice to also rename rcu_sync_sabotage() to rcu_sync_enter_start(), this
will save another change in cgroup.c, but this is minor.
Oleg.
