  rcu/tasks-trace: Handle new PF_IDLE semantics (2023-11-01 22:12:03 +0100)

----------------------------------------------------------------
RCU fixes for v6.7

* Fix a lock inversion between scheduler and RCU introduced
  in v6.2-rc4. The scenario could trigger on any user of RCU_NOCB
  (mostly Android and also nohz_full).

* Fix PF_IDLE semantic changes introduced in v6.6-rc3 breaking some
  RCU-Tasks and RCU-Tasks-Trace expectations as to what exactly is
  an idle task. This resulted in potential spurious stalls and
  warnings.

----------------------------------------------------------------
Frederic Weisbecker (3):
      rcu: Introduce rcu_cpu_online()
      rcu/tasks: Handle new PF_IDLE semantics
      rcu/tasks-trace: Handle new PF_IDLE semantics

Peter Zijlstra (1):
      rcu: Break rcu_node_0 --> &rq->__lock order
